Connector: grid connectivity module

This module has two main features: automatic determination of matching boundary conditions and overset grid connectivity. Overset grid connectivity can be computed in a few separated steps: the search for blanked cells (cells that lie into a given surface) [Fig], the overlap optimization step (maximize the blanking to get a minimum overlap between grids) [Fig] and the computation of interpolation coefficients.
