d2958044fd feat(frontends/lean): add multiple_instances command 
After this commit, Lean "cuts" the search after the first instance is
computed. To obtain the previous behavior, we must use the new command

          multiple_instances <class-name>

closes #370

5efadb09cc feat(library/tactic/inversion_tactic): improve 'cases' tactic for HoTT library 
This commit adds support for hypotheses (h : C As idxs) where the indices idxs
are just local constants. Before this commit the indices idxs had to be hsets.
Now, they can be hsets or local constants.

The new tests demonstrate new examples that can be handled by the
improved tactic in the HoTT library

Remove bogus constraint
     cs.push_back(mk_eq_cnstr(mk_app(maux_type, locals), type, j, relax));
This constraint is incorrect because 'type' may contain local constants that are not in 'locals'.

We just rely on
   cs.push_back(mk_eq_cnstr(mk_app(maux, margs), arg, j, relax));
When maux is assigned, the system will inforce that its type (which is based on maux_type) must be type correct
