First draft of math parser, without new matrix syntax
New matrix syntax, no longer blows the stack!
Matrices actually work
Minor fix
Add new tests, and make some of them pass
Make sure we consume the entire input
Actually delete the test files
Make division work
Refactor macros to use cases instead of separate parse methods
Rearrange the parser order to make precedence more obvious
Add superscripts, subscripts, and (untested) strings
Add a little note
