6 years agodecentralizing core notation

decentralizing core notation

centralized core notation (one single file) has two disadvantages:
- when some core notation is added the whole "world" must be recompiled
- unused core notation loaded in the parser gets in the way when defining contrib-specific notation
by defining core notation on a "one notation per file" basis:
+ every contrib file can load just the needed notation
+ sharing is possible as before in that two contrib files can load the same notation file

decentralalization will occur is stages:
this is the first stage meant to solve some issues in
+ lambdadelta (! blocked by fact)
+ certifiedRev (o{} blocked by compose, comprehension, singl, subset)
