Another change in the cone PDB file for the frame order models.

This affects all models.

Updated the pymol.cone_pdb() user function for the change to the cone PDB file.

Changed the design of the cone PDB object for the frame order models.

The change affects the models which consist of the full motional eigenframe.

Fixes for all of the frame order target functions which use the Scipy quadratic numerical integration.

Some fixes for the pseudo-ellipse frame order target functions.

Fix for many of the frame order target functions.

The Rx2_eigen matrix is a local, not class variable.

Created the pseudo-ellipse frame order test model data.

The Monte Carlo integration flag is now stored at cdp.mcint and is not set for the rotor model.

This allows the method to be programmatically changed.

A few small bug fixes for the old quadratic integration target functions.

Target and auxiliary functions are now available for both quadratic and Monte Carlo integration.

This can be set via the mcint flag to the maths_fns.frame_order initialisation code. In some cases
quadratic integration is faster or better, whereas in others the rough Monte Carlo technique is
better.
