Log:
Created two new frame order system tests for the torsionless isotropic cone
PDB representation file.
This is the two PDB files from the frame_order.pdb_model user function. The
two new system tests
are Frame_order.test_pdb_model_iso_cone_torsionless_z_axis and
Frame_order.test_pdb_model_iso_cone_torsionless_xz_plane_tilt.
