• New functions in ufc::finite_element: - evaluate_reference_basis - evaluate_reference_basis_derivatives - transform_reference_basis_derivatives - tabulate_reference_dof_coordinates
• New functions in ufc::dofmap: - num_global_support_dofs - num_element_support_dofs
• Improved docstrings for parts of ufc.h
