As we come up on the last iteration before midterms, I find myself
coming close to being able to parse any bash file.

I've finished combining the fragment ASTs that I wrote at the very
beginning of the summer into the main tree.  Also, I implemented a
missing feature (process substitutions) and added support for
associative arrays.  Finally, I added Functions to the tree, meaning in
theory I should have no major part of the bash grammar left to implement.

The result?

(I apologize for how poorly this "website" looks, it was just a quick
aggregation of the pictures and files I made for my iteration-end demo
this past weekend.)

The files parsed took some modifications (the purpose of generating
these pictures from real files was find out where the parser was
lacking).  Despite coming up with a fairly long list of minor fixes, the
resulting ASTs are readable and (hopefully usable).

So... what's up for this week?  Bug fixes.  Lots and lots of bug fixes.
 Little things that kept the files from being parsed exactly as they
were.  When I fix those, the AST creation will be complete (though it
might need a few updates if I find things are missing or not as easy to
work with).
