Improvements for all of the Frame_order.test_pdb_model_* system tests.

The rotate_from_Z() method has been introduced to simplify the determination of the 3D coordinates
expected for the PDB file. This will allow for more advanced testing of the PDB for the cone
models.

Renamed all of the Frame_order.test_pdb_model_* system tests to be more descriptive.

Created the Frame_order.test_pdb_model_iso_cone_xz_plane_tilt system test.

This checks the PDB file from the frame_order.pdb_model user function for the isotropic cone model
with a xz-plane tilt.

Printout fix for the axis in the Frame_order.test_pdb_model_iso_cone system test.

Fix for the representation label positions created by the frame_order.pdb_model user function.

The 'size' argument was not being used at all for the representation title
atoms. It is now passed into the add_titles() function as the displacement argument + 10 Angstrom.

Small fix for the Frame_order.test_pdb_model_iso_cone system test for the 'B' representation.

Fix for the cone sized created by the frame_order.pdb_model user function.

The 'size' argument was not being used at all for the cone size. It is now passed into the
lib.structure.represent.cone.cone() function as the 'scale' argument.

Created the Frame_order.test_pdb_model_iso_cone system test.

This is for checking the PDB representation of the isotropic cone frame order model created by the
frame_order.pdb_model user function. It checks both A and B representations.

Fix for the unit tests to match r26656 - Python 2.5 floats do not have a 'real' property.

Bug fix for the lib.structure.angles.angles_*() functions for odd increments.

This affects the PDB representations of the diffusion tensor and frame order when the number of
increments in the respective user functions is set to an odd number. It really only affects the
frame_order.pdb_model user functions, as the number of increments cannot be set in any of the other
user functions (structure.create_diff_tensor_pdb, structure.create_rotor_pdb,
structure.create_vector_dist, n_state_model.cone_pdb).
