Vidar Holen 76a39f254b 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.
