193a9d8cde refactor(library/norm_num): avoid manual constant name initialization 
@rlewis1988 We group all Lean constants used in the C++ code at
src/library/constants.txt

Jeremy and Floris check this file before renaming constants in the
library. So, they can quickly decide whether C++ code will be affected
or not.

We also have a python script for initializing the C++ name objects.
To use the script:
   - go to src/library
   - execute
       python ../../script/gen_constants_cpp.py constants.txt

It will create the boring initialization and finalization code, and
declare a procedure get_<id>_name() for each constant in the file constants.txt.

I also move the norm_num1.lean to the set of unit tests that are
executed whenever we push a commit to the main branch.

I found an assertion violation at line 606. Could you take a look?

Best,
Leo

9bedbbb739 refactor(library,hott): remove coercions between algebraic structures 
They are classes, and mixing coercion with type class resolution is a
recipe for disaster (aka counterintuitive behavior).

a618bd7d6c refactor(library): use type classes for encoding all arithmetic operations 
Before this commit we were using overloading for concrete structures and
type classes for abstract ones.

This is the first of series of commits that implement this modification

77d5657813 refactor(library/algebra/function): move function.lean to init folder 
Motivation: this file defines basic things such as function composition.

notation + coercions will behave as expected.

754276a660 feat(frontends/lean): round parenthesis for [tactic1 | tactic2] 
This commit also replaces the notation for divides
     `(` a `|` b `)`
with
      a `∣` b

The character `∣` is entered by typing \|
