Reverted r26467 as too much was committed.

The command used was:
svn merge -r26467:r26466 .

Fixes for all of the calculated double rotor model frame order matrix graphs.

The X and Y angles were mixed up. The first torsion half-angle sigma1 corresponds to a y-axis
rotation and the second sigma2 corresponds to a x-axis rotation.

Added the frame order matrix element graphs for the out-of-frame free rotor pseudo-ellipse model.

Added the frame order matrix element graphs for the in-frame free rotor pseudo-ellipse model.

Fixes for free rotor isotropic cone 1st degree frame order matrix graphs calculated using relax.

The 1st degree function accepts the cone opening angle theta rather than the order parameter S.

Added the free rotor pseudo-ellipse model to the frame order matrix element simulation script.

This only required the self.torsion_check variable to be set to False. The model uses the
inside_pseudo_ellipse() and rotation_hypersphere() methods.

Recreated all of the simulated pseudo-ellipse frame order matrix element graphs.

These are now in the Kronecker product notation so that they will match the graphs calculated using
the relax lib.frame_order.pseudo_ellipse module.

The change of r26447 which should have recreated the graphs was incorrect.

Fixes for the torsionless pseudo-ellipse 1st degree frame order matrix element graphs.

Bug fix for the torsionless pseudo-ellipse 1st degree frame order matrix.

The 11 element was of the wrong sign.

Added the torsionless pseudo-ellipse model to the frame order matrix element simulation script.

The generated Grace graphs containing the matrix values for 1,000,000 simulation values have been
added to the repository. The rotations are generated by the rotation_hypersphere_torsionless()
method and the angle violations checked using the inside_pseudo_ellipse() method.
