Refactoring, 25% speedup.
...
* Checks now use Writer monad instead of State
* Parser no longer emits notes unrelated to parsing.
* All checks are now passed a parameter value, containing shell type,
map from notes to parents and such. This eliminates recalculation
and removes the need for a special group of parent examining checks.
