Created a PDB distribution of CaM orientations for the free rotor frame order model.

This is a uniform set of rotations about the pivot-CoM axis.

Created a data directory for the free rotor CaM test model.

Modified the rigid frame order CaM test model script to properly test the PyMOL representation.

This is not a system test, but is to be used manually and visually to check that the PyMOL
representation created by relax of the average position, eigenframe, and cone is correct!

Created the Frame_order.test_cam_rigid system test and optimisation script.

Added a script for optimising the rigid frame order CaM test data.

The resultant average position PDB file and relax save file have also been added for reference.

Small fix for the tensor fitting script, and addition of the log file and output tensors.

Updated the alignment tensor fitting script.

Errors are now set on the RDCs and PCSs.

Created the RDC and PCS test data for the rigid frame order model.

Started to create some data for testing the frame order theory.

This will be used to generate synthetic data for all 9 models currently in relax.
