MESHADJACENCYMATRIX Compute adjacency matrix of a mesh from set of faces.

   ADJMAT = meshAdjacencyMatrix(FACES)
   Returns a sparse NV-by-NV matrix (NV being the largest vertex index)
   containing vertex adjacency of the mesh represented by FACES.
   FACES is either a NF-by-3, a NF-by-4 index array, or a Nf-by-1 cell
   array.

   Example
     [v f] = createCube;
     adj = meshAdjacencyMatrix(f);
