Olivier Parcollet fa07abbea9 [gfs] Singularity as an explicit template parameter
- change the underlying data : do not flatten the linear indices of the
  mesh into a single index, keep a higher dim array.
- easier for various places, and necessary for g(nu,nu').
- work on several 2 part. containers.
- add default target (may not be always matrix_valued)
