This PR is a WIP implementation of Geodesic Flow Kernel.

This method requires the Generalized SVD, and it is not implemented either in numpy or Scipy.
The transferlearning library uses bob.math.gsvd here, which has its custom C++ code here.

@antoinecollas Do you think you can implement gsvd as you want? Or we cannot implement this method?

No, I tried but the gsvd of the paper is hard to implement in python right now.
