% \section{Introduction}
%
% This package defines a \LaTeX\ thesis class for Drexel University
% conforming to the
% \href{http://www.library.drexel.edu/files/services_documents/thesismanual.pdf}
%   {Drexel University Thesis Manual version 2009/06/01}.
%
% \section{Usage}
%
% To write a thesis, you load the Drexel thesis definitions by loading
% the \pkg{drexel-thesis} class at the beginning of your
% \LaTeX\ document with the |\documentclass| command.  For example,
% \begin{example}
%   \documentclass{drexel-thesis}
% \end{example}
%
% \subsection{Options}
%
% \DescribeOptions{final,draft}
% The default option (selected if not options are passed) is
% \Lopt{final} mode, which has all the proper formatting and spacing
% for your final product. The other main option is \Lopt{draft} mode,
% which reduces all the spacing in the document, so might be helpful
% when printing out drafts (saves paper).
%
% \Lopt{final} mode corresponds to (with Thesis Manual chapter and
% verse) \\
% \begin{tabular}{r p{0.8\textwidth}}
%   \Lopt{oneside} & 1.5 Library Submission Information, Print
%     Version: ``All copies must be: \ldots Typed/printed on only one
%     side of the page (not double-sided).'' \\
%   \Lopt{finalspace} & Assorted single, double, and triple spacing
%   directives. \\
%   \Lopt{dottedtoc} & From the example on p17.
% \end{tabular}
%
% \Lopt{draft} mode corresponds to \\
% \begin{tabular}{r p{0.8\textwidth}}
%   \Lopt{twoside} & Save space. \\
%   \Lopt{draftspace} & Save space. \\
%   \Lopt{dottedtoc} & Might as well be consistent with \Lopt{final}. \\
%   \Lopt{mydraftwatermark} & It's good to have a timestamp. \\
% \end{tabular}
%
% \DescribeOption{subfig}
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/subfig/}{\pkg{subfig}}
% makes it easy to include and caption multi-part figures.  However,
% getting \pkg{subfig} to cooperate with \pkg{floatrow} and
% \pkg{tocloft} can be tricky.  If you want to use \pkg{subfig}, just
% pass the \Lopt{subfig} option to \cls{drexel-thesis}, and all the
% pesky details will be taken care of.  See Section
% \ref{sec:better-example} for an example.
%
% \DescribeOption{finalspace}
% Loosen spacing.
%
% \DescribeOption{draftspace}
% Tighten spacing.
%
% \DescribeOptions{dottedtoc,boldtoc,
%                  dottedpart,boldpart,
%                  dottedchapter,boldchapter}
% These options change how the relevant table of contents lines are
% printed.  \LaTeX\ defaults to bold but not dots.  The \Lopt{*toc}
% options set all of the types.  For example, \Lopt{boldtoc} is
% equivalent to \Lopt{boldchapter,boldpart}.
%
% \DescribeOption{draftwatermark}
% \Lopt{draftwatermark} adds ``DRAFT \meta{date}'' watermarks to each
% page.  A useful way to remember that the version you're looking at
% is not final.  Also helps reviewers tell you what version they're
% correcting.  Requires the \pkg{draftmark} package.
%
% \DescribeOption{mydraftwatermark}
% \Lopt{mydraftwatermark} is similar to \Lopt{draftwatermark} but
% depends on the possibly more common \pkg{xcolor}, \pkg{eso-pic},
% and \pkg{graphicx}.
%
% \DescribeOption{indentfirst}
% \Lopt{indentfirst} indents the first paragraph after sections etc.
%
%
% \subsubsection{Interesting \cls{book} options}
% 
% \DescribeOption{oneside}
% Setup output for one-sided printing.
%
% \DescribeOption{twoside}
% Setup output for two-sided printing.
%
% \DescribeOption{leqno}
% \Lopt{leqno} places the numbering of formulae on the left hand side
% instead of the right.
%
% \DescribeOption{fleqn}
% \Lopt{fleqn} typesets displayed formulae left-aligned instead of
% centered.
%
%
% \subsection{Macros}
%
% \begin{command}
%   `\cs{author}\marg{name}'
% \end{command}
% \DescribeMacro{\author}
% Use this macro to set your full name to \meta{name}, including
% your middle initial or name.  For example
% \begin{example}
%   \name{Richard P. Feynman}
% \end{example}
% See the Manual 3.1 p8.
%
% \begin{command}
%   `\cs{title}\marg{title}'
% \end{command}
% \DescribeMacro{\title}
% Use this macro to set your thesis title to \meta{name}.  For example
% \begin{example}
%   \title{A New Approach to Quantum Theory}
% \end{example}
% See the Manual p16.
%
% \begin{command}
%   `\cs{advisor}\marg{name}'
% \end{command}
% \DescribeMacro{\advisor}
% Use this macro to set your advisor's name to \meta{name}.  For
% example
% \begin{example}
%   \advisor{John A. Wheeler, Ph.D.}
% \end{example}
% You can set multiple advisors, if appropriate, by calling |\advisor|
% multiple times.
% \begin{example}
%   \advisor{John A. Wheeler, Ph.D.}
%   \advisor{Advisor 2}
% \end{example}
% See the Manual 3.1 p8.
%
% \begin{command}
%   `\cs{defmonth}\marg{month}'
%   `\cs{defyear}\marg{year}'
% \end{command}
% \DescribeMacro{\defmonth}
% \DescribeMacro{\defyear}
% Use these macros to set the month with \meta{month} (spelled out)
% and year with \meta{year} (four digits) of your thesis defense.  For
% example
% \begin{example}
%   \defmonth{June}
%   \defyear{1942}
% \end{example}
% See the Manual 3.1 p8.
% The |def| in |\def*| avoids collisions with the plain \TeX\ 
% |\month| and |\year| (see the
% \href{http://www.tug.org/utilities/plain/cseq.html#month-rp}{month}
% and
% \href{http://www.tug.org/utilities/plain/cseq.html#year-rp}{year}
% entries in the HTML version of David Bausum's \emph{TeX Reference
% Manual}).
%
% \begin{command}
%   `\cs{degree}\marg{degree}'
% \end{command}
% \DescribeMacro{\degree}
% Set your target degree with \meta{degree}.  From the Manual 3.1 p8.
% \begin{quote}
%   Write out the name of the degree for which you are a candidate.
%   All Ph.D.\ candidates must use |Doctor of Philosophy|.  All
%   Master's degree candidates should use the precise degree name
%   (e.g., |Master of Science in Mechanical Engineering|).
% \end{quote}
% So, for a Ph.D candidate,
% \begin{example}
%   \degree{Doctor of Philosophy}
% \end{example}
%
% \begin{command}
%   `\cs{copyrighttext}\marg{text}'
% \end{command}
% \DescribeMacro{\copyrighttext}
% Use this macro to set the copyright text to \meta{text}.
% The default value is ``All Rights Reserved.''.
% \begin{example}
%   \copyrighttext{Released to the Public Domain.}
% \end{example}
% See the Manual 3.2 p9.
%
% \begin{command}
%   `\cs{copyrighttextCC}'
% \end{command}
% There are a number of predefined copyright messages for ease of use \\
% \begin{tabular}{l l}
%   |\copyrighttextCC| & Creative Commons copyright \\
% \end{tabular}
%
% \begin{command}
%   `\cs{tableofcontents}'
% \end{command}
% \DescribeMacro{\tableofcontents}
% Write the table of contents (Manual 3.5 p9).  You can control the
% verbosity by setting |\tocdepth| according to the following table
% (\href{http://www.image.ufl.edu/help/latex/intext.shtml}{source}). \\
% \begin{tabular}{l l l}
%   Depth in document & Section Command & Depth for |\secnumdepth| Command \\
%   -1 & |\part| & 1 \\
%    0 & |\chapter| & 2 \\
%    1 & |\section| & 3 \\
%    2 & |\subsection| & 4 \\
%    3 & |\subsubsection| & 5 \\
%    4 & |\paragraph| & 6 \\
%    5 & |\subparagraph| & 7
% \end{tabular} \\
% For example, to expose everything down to and including the
% |\subsection| level, you would add
% \begin{example}
%   \setcounter{tocdepth}{2}
% \end{example}
% to your preamble (the section before |\begin{document}|, not the
% |preamble| environment discussed below).
%
% Note that the Manual 3.5 p9 requires ``List chapter titles and at
% least the first and second order subdivisions.'', which corresponds
% to a |\tocdepth| of at least 2.
%
% \begin{command}
%   `\cs{listoftables}'
% \end{command}
% \DescribeMacro{\listoftables}
% Write the List of Tables page (Manual 3.6 p10).
% Skip if you have no tables in your thesis.
%
% \begin{command}
%   `\cs{listoffigures}'
% \end{command}
% \DescribeMacro{\listoffigures}
% Write the List of Figures page (Manual 3.7 p10).
% Skip if you have no figures in your thesis.
%
% \begin{command}
%   `\cs{blanklines}\marg{num}'
% \end{command}
% \DescribeMacro{\blanklines}
% Insert \meta{num} blank lines.  For example
% \begin{example}
%   \blanklines{2}
% \end{example}
% The skipped lines are always \emph{single spaced} lines, regardless
% of the current line spacing in the environment calling this macro.
%
%
% \subsection{Environments}
%
% \DescribeEnv{preamble}
% Generalize the |\frontmatter| for the thesis, setting up page
% numbering, including the title page, copyright page etc.  The
% |preamble| environment should contain the following elements
% (in order, see the Manual p8)
% \begin{itemize}
%   \item |dedication| environment (optional)
%   \item |acknowledgments| environment (optional)
%   \item |\tableofcontents|
%   \item |\listoftables|
%   \item |\listoffigures|
%   \item |abstract| environment
% \end{itemize}
% This will take care of everything from the title page (Manual 3.1),
% up through the blank page before the text (Manual 3.9).
%
% \DescribeEnv{dedications}
% Set the dedications text.
% Highlights from the Manual 3.3 p9:
% \begin{quote}
%   The |Dedications| page is optional.
% \end{quote}
%
% \DescribeEnv{acknowledgments}
% Set the acknowledgments text.
% Highlights from the Manual 3.4 p9:
% \begin{quote}
%   The |Acknowledgments| page is optional, but most theses do
%   include a brief statement of thanks or recognition of any special
%   assistance.
% \end{quote}
%
% \DescribeEnv{abstract}
% Set the thesis abstract text.  In the Thesis Manual, see section 3.8
% Abstract (p10) for details, p20 for an example.
%
% Highlights from the Manual:
% \begin{quote}
%   The abstract is a summary that allows readers to determine the
%   value of reading the full thesis.  It should include a statement
%   of the problem, an outline of procedures or methods, and a summary
%   of results and conclusions.
% \end{quote}
% \begin{itemize}
%   \item Word limits: 600 for a Master's thesis, 350 for a Ph.D.\ thesis.
% \end{itemize}
%
% \DescribeEnv{thesis}
% Set the thesis text.  In the Thesis Manual, see section 3.10 Thesis
% (p11) for details.
%
% Highlights from the Manual:
% \begin{quote}
%   Divide the text into its major parts/chapters/subsections.  No
%   fixed arrangement is necessary.  The major parts may contain such
%   subjects as introduction, general argument, description of
%   experimental procedures, research methods, discussion, summary,
%   conclusions, recommendations, and other pertinent topics that are
%   necessary for a complete understanding on the part of a
%   sophisticated or professional reader.
% \end{quote}
%
% \DescribeEnv{vita}
% Set the thesis vita text (Ph.D.\ only).  See the Manual 3.15 p12,
% ``Vita'', for details.
%
% Highlights from the Manual:
% \begin{quote}
%   The Vita is a biography of the student written in the third person
%   in either essay or outline form.  It should include the full name,
%   place and date of birth (optional), country of citizenship
%   (optional), institutions attended, degrees and honors received,
%   titles of publications, teaching and professional experience, and
%   other pertinent data.  The Vita must be one page or less.
% \end{quote}
%
%
% \subsection{Hints}
%
%
% \subsubsection{Package installation}
% \label{sec:dependencies}
%
% All the packages this class depends on must be installed somewhere
% in your texmf tree (they probably already are).  If not, you will
% recieve warning messages on compilation such as
% \begin{example}
%   ! LaTeX Error: File `missing-package.sty' not found.
% \end{example}
% You should then install the missing package(s) using your operating
% systems package manager, or grab the missing package from
% \href{http://www.ctan.org/}{CTAN}, and install them following TODO.
%
%
% \subsubsection{Tables and Figures}
%
% \pkg{drexel-thesis} loads
% \href{http://www.ctan.org/tex-archive/macros/latex/required/graphics/}{\pkg{graphicx}}
% to define the |\includegraphics| macro,
% \href{http://www.ctan.org/tex-archive/macros/latex/required/caption/}{\pkg{caption}}
% for pretty caption formatting, and
% \href{http://www.ctan.org/tex-archive/macros/latex/required/floatrow/}{\pkg{floatrow}}
% for placing captions.
%
% Simple float definitions will look like
% \begin{example}
%   \begin{table}
%      \caption{Some caption text}
%      \begin{tabular}{...}
%        ...
%      \end{tabular}
%   \end{table}
% \end{example}
% or
% \begin{example}
%   \begin{float}
%      \includegraphics{...}
%      \caption{Some caption text}
%   \end{float}
% \end{example}
% For more useful float information, see the examples in Section
% \ref{sec:better-example-part} and the
% \href{http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions}
%   {\LaTeX\ wikibook page}.
%
%
% \subsubsection{Citations}
%
% I highly recommend using \BibTeX\ and
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/natbib/}{\pkg{natbib}}.
% See Section \ref{sec:better-example} for a simple example.
%
% Suggested options:\\
% \begin{tabular}{r p{0.8\textwidth}}
%   |super| & selects citations in superscript mode. \\
%   |sort&compress| & automatically sorts and compresses compound
%     citations (|\pcite{a,b,...}|).
% \end{tabular}
%
%
% \subsubsection{References}
%
% Easier cross referencing with
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/cleveref/}{\pkg{cleveref}}.
% Is a wonderful tool for easy, consistent crosslinking via |\cref|,
% |\Cref|, etc..  The manual is also very good.
% Note that if you use |\part|s in your document, you need to tell
% \pkg{cleveref} how to deal with them:
% \begin{example}
%   \usepackage{cleveref}
%   \crefname{part}{part}{parts}
% \end{example}
%
%
% \subsubsection{Hyperlinks}
%
% \cls{drexel-thesis} loads
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/hyperref/}{\pkg{hyperref}}.
% with the options:\\
% \begin{tabular}{r p{0.8\textwidth}}
%   |colorlinks| & color the link letters instead of drawing colored boxes. \\
% \end{tabular}
%
% If running with a pdftex-based driver, |\author|, |\title|, and
% |\degree| automatically set |pdfauthor|, |pdftitle|, and
% |pdfsubject| respectively.  You can use the |\hypersetup| macro to
% set options overriding these defaults.
%
%
% \subsubsection{Developing large \LaTeX\ documents}
%
% A thesis may take a while to compile, especially if it contains
% lots of images, etc..  One way to save time, is to use |\includeonly|
% when including chapter \file{*.tex} files (see
% \href{http://en.wikibooks.org/wiki/TeX/includeonly}{the \TeX\ Wikibook}).
% Usage would be something like
% \begin{example}
% \documentclass{drexel-thesis}
% ...
% \includeonly{chapter2.tex,chapter3.tex}
% \begin{document}
% ...
% \begin{thesis}
% \include{chapter1.tex}
% \include{chapter2.tex}
% \include{chapter3.tex}
% \include{chapter4.tex}
% \end{thesis}
% ...
% \end{document}
% \end{example}
% which would only compile chapters two and three.  Don't confuse the
% similar commands |\include| and |\input|.  The more fundamental
% |\input| just inserts the file contents at that point, while
% |\include|
% \begin{itemize}
%   \item may only be used after |\begin{document}|
%   \item acts like |\clearpage \input{} \clearpage|
%   \item will not crash on nonexistent files
% \end{itemize}
%
%
% \StopEventually{\pagebreak\PrintChanges}
%
%
% \section{Implementation}
%    \begin{macrocode}
%<*class>
%    \end{macrocode}
%
% For simplicity, we'll derive everything from the standard \cls{book}
% class.
%
%
% \subsection{Option Processing}
%
% Include
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/xkeyval/}{\pkg{xkeyval}}
% for easier option parsing.  If the package is not installed on your system,
% see Section \ref{sec:dependencies} for installation instructions.
%    \begin{macrocode}
\RequirePackage{xkeyval}
%    \end{macrocode}
%
% Define some booleans to store option states
%    \begin{macrocode}

% \subsection{Internal package includes}
%
%
% Include some other packages we'll need.  If the package is not
% installed on your system, see Section \ref{sec:dependencies} for
% installation instructions.
%
% For many packages, we want the same functionality for both
% \Lopt{final} and \Lopt{draft} modes.  We pass \Lopt{final} to most
% of those packages to override a possible \Lopt{draft} option passed
% to \pkg{drexel-thesis}.
%
%
% \subsubsection{\pkg{setspace}}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/setspace/}{\pkg{setspace}}
% for double spacing.
%    \begin{macrocode}

%
%
% \subsubsection{\pkg{calc}}
%

% a thesis without figures.
%    \begin{macrocode}
\RequirePackage[final]{graphicx}
%    \end{macrocode}
%
% We include the graphicx package now so we can
% pass \Lopt{final}, because some later packages include it with no options,
% and a \Lopt{final} include after that produces errors like
% \begin{example}
%   l.104 \RequirePackage
%                        [final]{ifpdf}
%   The package graphicx has already been loaded with options:
%     []
%   There has now been an attempt to load it with options
%     [final]
% \end{example}
%
%
% \subsubsection{\pkg{draftmark}}
%
% The Comp.~Sci.\ class used
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/draftcopy/}{\pkg{draftcopy}}
% to add their watermarks, but as of the current 2002/02/25 v2.16, it
% uses postscript specials, and so doesn't work with pdf\LaTeX.
% Instead we use the recent (catalogued 2009/11/03)
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/draftmark/}{\pkg{draftmark}}
% which unfortunately has a number of apparently non-standard dependencies
% (\href{http://www.ctan.org/tex-archive/macros/latex/contrib/etextools/}{\pkg{etextools}},

%  \href{http://www.ctan.org/tex-archive/macros/latex/contrib/xifthen/}{\pkg{xifthen}},
%  if only I had the space to install |texlive-latexextra| |:p|).
% The output is, however, very flexible, and it \emph{does} work with
% both \LaTeX\ and pdf\LaTeX.  If you don't like the default watermark,
% you can also adjust the particulars with |\draftmarksetup|.
%    \begin{macrocode}

% |\floatsep| is the space between adjacent floats that are moved
% to the top or bottom of the text page.
%
% |\textfloatsep| is the space between the main text and floats
% at the top or bottom of the page.
%
% |\intextsep| is the space between in-text floats and the text.  We
% don't bother overriding this one, because we've handled it with
% \pkg{floatrow} in Section \ref{sec:floatrow}.
%
% From the Manual 2.3 p6, ``Tables and Figures''

% following:
% \begin{itemize}
%   \item reset the section and subsection counters to zero,
%   \item redefine |\thesection| to produce alphabetic appendix
%         numbers. This redefinition is done globally to ensure that it 
%         survives even if |\appendix| is issued within an environment such
%         as \texttt{multicols}.

% In addition to \cls{book}'s (or \pkg{hyperref}'s) activity, we
% fiddle with the \pkg{tocloft} chapter settings add switch to global
% double-spacing.

% and therefore lacks a |\numberline| section in its \file{*.toc}
% entry.
%
% We increase |numwidth| to 6.5em to make room for |Appendix~| before
% the chapter number/letter, and add a colon after it.
%
% The |\protect| calls get the macros into \file{*.toc} unexpanded, so

% \section{Known bugs and issues}
%
%
% \subsection{Hacks}
%
% \begin{itemize}
%   \item |\vspace*{0\p@}| space between page top and chapter
%     headings (|\@makechapterhead| and |\@makeschapterhead|,
%     Sec.~\ref{sec:implement-chapters}).
%   \item Extra space under LOT and LOF titles compared to TOC.
%     (Secs.~\ref{sec:implement-lof} and \ref{sec:implement-lot}).
% \end{itemize}
%
%
% \subsection{Bugs}
%
% \begin{itemize}
%   \item Different space between chapter heading and section heading,
%     vs.\ chapter heading and text.  Compare \emph{A Chapter Heading}
%     and \emph{Another Chapter} in \file{example.pdf}.  This is a
%     problem (although with opposite order) in the \cls{book} class
%     itself.  For example, compile
%     \begin{example}
%\documentclass{book}
%\begin{document}
%\chapter{Chapter with text}
%Bla bla bla.
%\chapter{Chapter with section}
%\section{Section}
%Bla bla bla.
%\end{document}
%     \end{example}
%   \item Footer overlap if chapter/section names are particularly long.
%     See \emph{Section in long-titled chapter} in \file{example.pdf}.
%     Workaround: turn off either chapters or sections in the footer.
%     \begin{example}
%       \fancyfoot[RE,LO]{\scshape\leftmark}
%       \fancyfoot[LE,RO]{}
%     \end{example}
