Splitting Term into five unrelated interfaces:

1. sorts.ml: A small file utility for sorts;

2. constr.ml: Really low-level terms, essentially kind_of_constr, smart
constructor and basic operators;

3. vars.ml: Everything related to term variables, that is, occurences
and substitution;

4. context.ml: Rel/Named context and all that;

5. term.ml: derived utility operations on terms; also includes constr.ml
up to some renaming, and acts as a compatibility layer, to be deprecated.
