---------------------------+-----------------------------------------------
From the discussions of (TODO: add refs to the threads in sage-devel),
there is a consensus that, at this point, the `combinatorial_map`
decorator should by default return the decorated method as is, in
order to have no impact on speed. On the other hand, projects built on
top of Sage, like findstat are welcome to customize locally this hook to
instrument
the Sage code and exploit the semantic information provided by this
decorator.
This ticket therefore:
- Defines `combinatorial_map` as a no-op
- Discuss the purpose of this decorator
- Uses the previous implementation as an example of how to customize
`combinatorial_map`
Note: this change is slightly backward incompatible since
`combinatorial_maps_in_class` is not functional any more by default.
