Title: WIP: Ply Parser

Replace the SPARK parser with one using PLY

TODO (in decreasing priority):
* Fix Sqrt formatting (`Sqrt[x]` presently formatted as `x^(1 / 2)`).
* Fix misc. pattern parsing issues.
* Figure out what's going wrong when loading `Import` definitions.
* Map `DifferentialD` token to `dx` during `TeXForm`. (`additional_entities` ???)
* Add some more parsing benchmarks (and write up comparison with SPARK parser).
