Resigned the internal structural object atom_loop() method to be up to 20 times faster.

The base model_loop() method is no longer used at all. It was previously being used in a nested
fashion, making the loop extremely slow when lots of models exist.

The alignment tensors for the pseudo-ellipse test data have now been calculated.

Performed the frame order analysis on the pseudo-ellipse test data.

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.
