Naive question: is there really a usecase for this parameter ?

Mostly for interpolation:

In our fMRI application, all subjects are assigned the same weight. However other FUGW users might do fancier things...

I removed it since there is no immediate usecase where it could be relevant for the end user.

AN old traidiotn of sklearn is that fit() return the object itself.

Solves #58, #77 and #78.
Adds a new set of tests against POT and in the identity case. Fixes the barycenter weight mix-up issue in the dense case.
It might be worth opening another PR for the sparse case.
