3fb2d8bbc0 feat(library/tactic/inversion_tactic): use the "simpler" compilation approach in more cases 
The approach implemented in the commit 8974d70c11ef7b9b2c5d can be
extended to indexed inductive families. See comments in the code.

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

expected by the tactic framework.
