script/save_basis.py: fix mesh mode, make permutations directly from mesh
script/plot_mesh.py: fix help message
Vector to radial mesh operations
generalize dict_to_array() for nD arrays
fix type errors under Windows: in nm.take() cells -> nm.int32(cells)
remove unused argument
fix get_facet_dof_permutations(), H1NodalMixin._setup_facet_orientations()

- permutations should come from facet nodes in reference order
- fixes #205
increase approximation orders of 3_4, 3_8 in tests/test_poly_spaces.py
prevent building ori_map for higher order elements in FESurface.__init__()
orthogonalization
Piecevise radial vector smoothing.
Orthogonalization (can return gs. coeficienf, bugfixies)
