Grammar Spring Cleaning

The Grammar Spring Cleaning algorithm goes through a grammar implemented in TDL and removes types that do not have an impact on the competence of the grammar. It is combined with a grammar compression algorithm, implemented by Yi Zhang, that counts the minimum types needed to create an equivalent grammar, where equivalent grammars refers to grammars that return the same set of analyses for the same input string (which may be the empty set).
