General TODOs:
* "Der man iz gut-er" is parsing!!!!
* how to implement 'want'? like 'can'? does this generalise to v_vp verbs?
* add interrogative comp verbs into lexicon
* pronoun and nit inversion not implemented
* what's with ton in the singulative section of test suite.
* hook habitual ton aux up to inflection
* make unmarked sentences be constrained for aspect - add ton again
   - same for tense in Es tut mir vey.
* conjugation is completely and utterly not working
* add aux + adv + PP etc examples to testsuite
* ze ikh gut | still getting two parses, rules can apply in either order.
* AUXs are not specifying form of aux verb
* prevent adjective + pronoun: eg "Gut-e Ikh zing"
* der man zing-t nit | has two parses
* ADV + VSO / VSO + ADV | has two parses
  - gut ze Ikh dem man
* find example of V aux in interrogative, then implement 
* looks like the -t in the PP is squeezing through without ge-
* Seperates lex-types into `le_types.tdl`.
* Not getting SPECI for a sentence... which one??

Low priority
* abstract away agreement constraint patterns from irregular verbs etc
* are VOS interrogatives grammatical?
* get case on nouns working
* figure out neuter definite vs absolutive
