Move computation of reordering of dofs on faces based on alignment to
new module alignment. Looks like it's working now, but not tested with
DOLFIN yet.

Example output for degree 6 Lagrange on tets:

void dofmap(int dofs[], const Cell& cell, const Mesh& mesh) const
{
  static unsigned int face_reordering[] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 4, 7, 9, 1, 5, 8, 2, 6, 3, 3, 6, 8, 9, 2, 5, 7, 1, 4, 0, 3, 2, 1, 0, 6, 5, 4, 8, 7, 9, 9,
 7, 4, 0, 8, 5, 1, 6, 2, 3, 9, 8, 6, 3, 7, 5, 2, 4, 1, 0};

  dofs[0] = cell.nodeID(0);
  dofs[1] = cell.nodeID(1);
  dofs[2] = cell.nodeID(2);
  dofs[3] = cell.nodeID(3);
  int alignment = cell.edgeAlignment(0);
  int offset = mesh.noNodes();
  dofs[4] = offset + 5*cell.edgeID(0) + ( alignment == 0 ? 0 : 4 );
  dofs[5] = offset + 5*cell.edgeID(0) + ( alignment == 0 ? 1 : 3 );
  ...
  alignment = cell.faceAlignment(0);
  offset = offset + 5*mesh.noEdges();
  dofs[34] = offset + 10*cell.faceID(0) + face_reordering[alignment*10 + 0];
  dofs[35] = offset + 10*cell.faceID(0) + face_reordering[alignment*10 + 1];
  dofs[36] = offset + 10*cell.faceID(0) + face_reordering[alignment*10 + 2];
}
