The 1st pseudo-ellipse torsion angle value in the frame order matrix graphs is now 0.0.

Only the cone opening angles set to 0.0 cause a failure in the pseudo-ellipse models, so the torsion
angle is now allowed to start at exactly zero.

The 1st angle for the calculated frame order matrix graphs is 0 for all non pseudo-ellipse models.

This is for the frame_order_solution.py script. Only the pseudo-ellipse models where numerical
integration is required fail for the angle of 0.0. Therefore the changing of the first angle from
0.0 to 0.01 only occurs for the pseudo-ellipse models. All graphs have been updated.

Fix for r26460 - the second factor also needs to be inverted.

A divide by zero fix for the free rotor pseudo-ellipse.

This is in the compile_2nd_matrix_pseudo_ellipse_free_rotor() relax library function.

A divide by zero fix for the torsionless pseudo-ellipse.

This is in the compile_2nd_matrix_pseudo_ellipse_torsionless() relax library function.

Added the frame order matrix element graphs for the double rotor model.

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 .
