We now store some typing information on constructors and cases to avoid type-unsafe optimisations. This will be either the type of the applied constructor or the type of the head of the match.

Nota : the constructor MLtuple and the extension of MLcase to general patterns have been proposed by P.N. Tollitte for his Relation Extraction plugin. MLtuple is currently not used by the main extraction, as well as deep patterns.
