b35abcc6a8 refactor(library): rename strategy "msimp" ==> "inst_simp" 
"inst_simp" means "instantiate simplification lemmas"
The idea is to make it clear that this strategy is *not* a simplifier.

0148bb08fd feat(library/blast): add 'ematch_simp' strategy for blast and msimp shortcut for it. 
This strategy is based on ematching and congruence closure, but it uses
the [simp] lemmas instead of [forward] lemmas.

f177082c3b refactor(*): normalize metaclass names 
@avigad and @fpvandoorn, I changed the metaclasses names. They
were not uniform:
- The plural was used in some cases (e.g., [coercions]).
- In other cases a cryptic name was used (e.g., [brs]).

Now, I tried to use the attribute name as the metaclass name whenever
possible. For example, we write

   definition foo [coercion] ...
   definition bla [forward] ...

and

  open [coercion] nat
  open [forward] nat

It is easier to remember and is uniform.

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

7d72c9b6b5 refactor(library/algebra/{field,ordered_field}, library/*): more renaming, setting implicit arguments 
Many theorems for division rings and fields have stronger versions for discrete fields, where we
assume x / 0 = 0. Before, we used primes to distinguish the versions, but that has the downside
that e.g. for rat and real, all the theorems are equally present. Now, I qualified the weaker ones
with division_ring.foo or field.foo. Maybe that is not ideal, but let's try it.

I also set implicit arguments with the following convention: an argument to a theorem should be
explicit unless it can be inferred from the other arguments and hypotheses.
