moved a lot of files to folders that will mesh with the directory structure intended...

W. Trevor King: I removed everything from the original 00149bc except
the 1-Shell -> shell move.

diff --git a/1-Shell/Readme.md b/shell/Readme.md
similarity index 100%
rename from 1-Shell/Readme.md
rename to shell/Readme.md

diff --git a/1-Shell/hello b/shell/hello
similarity index 100%
rename from 1-Shell/hello
rename to shell/hello
