46149d0d50 refactor(library/data/prod): break into pieces to reduce dependencies 
prod is needed for some automatically generated constructions.
So, it is important it is loaded in the environment as early as possible.

b5e0ded163 feat(frontends/lean): max precedence used by Lean is not max_uint anymore 
The motivation is to allow users to define notation with higher
precedence than function application.

ed83b7ff2a fix(emacs/lean-syntax): syntax highlight, issue #306 
1- FIXED     structure foo := (bar : Type) -- the name of structures is not highlighted
2- NOT FIXED check foo-- this comment is not highlighted
3- FIXED     check Type.{5} -- Type is not highlighted
4- FIXED     definition bar{thisishighlighted : Type} := foo
5- FIXED     definition bar2 {thetypeofthisvariableisnothighlighted :Type} := foo

Have no idea what is going on with 2. I'm not sure if this is our bug,
or Emacs code we depend on.

e499f8e20a feat(kernel/inductive): relax conditions for an inductive datatype in Prop to be able to eliminate into Type 
The new relaxed version allows us to define the "accessability"
proposition and have an eliminator into Type.

See justification in the new comments at inductive.cpp

8723f5b613 fix(frontends/lean/inductive_cmd): inductive datatype elaborator was 'fixing' parameter mismatches. 
Given a datatype C with parameters As, if the declaration contained
(C Bs), the elaborator would silently replace it with (C As).

This bug would confuse users and make them believe they define something
different.

d306c42a1f refactor(library/logic): cleanup some of the proofs in cast.lean, remove piext axiom 
Remark: the main motivation for piext was Lean 0.1 simplifier.
We are using a different approach in Lean 0.2.
The axiom is not needed anymore.
It is also not used in any part of the standard library
