remove all faces that are not connected to any elements
be careful this implies that the number of faces and the faces ids are no more
connected: we may have face ids that are greater than the number of faces.
Hence we need to be also careful with the face dof table which can no be be a
multi array but an unordered map
big change in dof table that handle non contiguous element and face ids
works on laplacian and stokes an 1D 2D 3D
need more tests
