Method needs_dof_transformations

Check if DOF transformations are needed for this element. DOF transformations will be needed for elements which might not be continuous when two neighbouring cells disagree on the orientation of a shared sub-entity, and when this cannot be corrected for by permuting

        permuting the DOF numbers on each cell.
