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 support for the double rotor model to the frame order matrix element simulation script.

The double rotation is constructed in the new rotation_double_xy_axes() method, and the checks for
the violation of the two torsion angles in the inside_double_rotor() method. In the main loop, the
theta, phi and sigma angles correspond to sigma1, sigma2, and nothing.

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.
