GRIDFACE Generate grid cell face numbering.

[ F, FV ] = GRIDFACE( C, B ) Generates an array F with global face numbers and FV with grid point indices per face. Input data is an array C with cell connectivities, and optionally the boundary struct B if upper triangular (OpenFOAM) ordering should be used (default normal ordering).

Input       Value/(Size)           Description
c           (n_v,n_c)              Cell connectivity pointer array where the
                                   entries in each column correspond to the
                                   cell vertex numbers specifying the cells.
b           struct                 Boundary struct to use upper triangular ordering
Output      Value/(Size)           Description
f           (n_f,n_c)              Array with global face numbers for all cells.
fv          (n_f,3/4)              Array with indices to vertices for each face.
