Makefile: Use the cyclic 'hsv' color map for angle-vs-y0-E.png
This avoids an artificial discontinuity where the angle wraps around
from -pi to +pi.

Makefile: Make Python interpreter configurable
For example, my default Python is 3.2, but I only have Matplotlib
installed for 2.7. However, the default version of Python on newton
is 2.6. Now the user can override it at invocation:
$ make PYTHON=python2.6 all

energy.gp: Add gnuplot script and rules to build an energy
W. Trevor King [Wed, 13 Feb 2013 16:30:42 +0000 (11:30 -0500)]
K should be 10, not -5
The homework calls for an energy barrier of five units.
W. Trevor King [Wed, 13 Feb 2013 01:47:32 +0000 (20:47 -0500)]
phase.gp: Add gnuplot script and rules to build a phase-space plot
In phase.gp, I use a for loop to iterate over data block (in this
case, each trajectory is in its own block). This gives you nice
per-block colors, but means you'll have to update the loop if you
change the number of energies you're looping over.
W. Trevor King [Wed, 13 Feb 2013 01:13:15 +0000 (20:13 -0500)]
error.gp: Add gnuplot script and rules to build an error-scaling plot
As requested in the homework. I didn't bother writing a stand-alone
script for building the data files, although you could split my
error-%.data rule out into its own script if you wish.

Currently it is hard-coded to read column five, but adding a command

safe-strto-example.c: Add a pared-down argv-parsing example
W. Trevor King [Wed, 23 Jan 2013 20:14:17 +0000 (15:14 -0500)]
safe-strto.c: Add safe_strtoc() for parsing complex arguments
Because people may wish to use safe-strto on systems that don't
support the more recent complex.h (from C99) or may wish to avoid
linking to libm, I've masked code related to safe_strtoc() behind
HAVE_COMPLEX. If you define this symbol, you get safe_strtoc(), but
have to link against libm. If you don't define this symbol, you don't
get safe_strtoc().
To turn on the symbol for this project, I've created config.h.
Usually such a config header would be created via the GNU Autotools
suite (e.g. `./configure`).
