d8f3bcec67 feat(library/init/logic): add 'arbitrary' 
It is identical to default, but it is opaque.
That is, when we use 'arbitrary A', we cannot rely on the particular
value selected.

4781fc8365 fix(library/init/logic): eq.symm should not use eq.subst 
Reason: eq.symm is used by definitional package, and eq.subst is opaque.
Thus, computation will get stuck if it depends on eq.subst.

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

fec45abda5 feat(library/hott): multiple changes in the HoTT library 
Jakob accidentally undid some of my changes in commit aad4592, reverted that;
made style changes in multiple files;
in types/sigma: finished porting Coq-HoTT, and finished unfinished proof;
in axioms/funext: rename path_forall, make arguments implicit and make instance visible

05f27b8f0e feat(frontends/lean/structure): add option for controlling whether we automatically generate eta and projection-over-intro theorems for structures 
It seems most of the time these theorems are not used at all.
They are just polluting the namespace.
