Added all of the Grace graphs produced by the frame_order_solution.py script.

These are the graphs of the 1st and 2nd degree frame order matrix elements, calculated using the
functions in lib.frame_order.

Redesign of the frame_order_solution.py script for calculating the frame order matrix elements.

This script now loops over all models, all motional frame orientations, and all order parameters to
generate the Grace graphs of all 1st and 2nd degree frame order matrix elements. Therefore the
script only needs to be executed once. The script also now calculates a point at zero (slightly
shifted to 0.01 to avoid artifacts).

Modified the frame order matrix Grace graph to EPS/PNG format conversion script.

Grace is now used to create a PostScript file and then the ps2eps program is called to convert to
EPS. This produces much better EPS files for inclusion into LaTeX documents.

Modified the frame order matrix Grace graph to EPS/PNG format conversion script.

The binary being called is now 'grace' rather than 'xmgrace'. This allows different Grace versions
to be used.

Created an executable Python script for mass converting the frame order matrix Grace graphs.

The script converts the *.agr files to EPS and PNG files.

Fix for the compile_1st_matrix_pseudo_ellipse() function.

This function of the lib.frame_order.pseudo_ellipse module now can rotate the 1st degree frame order
matrix out of its eigenframe and into the PDB frame.

Modified the rotate_daeg() function as this is independent of the degree of the frame order matrix.

This is the lib.frame_order.matrix_ops.rotate_daeg() function.

Removed some unused code in the pseudo-ellipse 2nd degree frame order matrix function.

This is the compile_2nd_matrix_pseudo_ellipse() function in the lib.frame_order.pseudo_ellipse
module. The change should make the RDC part of the frame order analysis for the pseudo-ellipse
model slightly faster.

Zero values can now be handled in the pseudo-ellipse 1st degree frame order matrix function.

This is in lib.frame_order.pseudo_ellipse.compile_1st_matrix_pseudo_ellipse().

Updated the frame_order_solution.py script for directly calculating the frame order matrix elements.

The MODEL variable has been added in preparation for supporting all model types, and this is now
added to the file name. The Grace header is now also being automatically generated and this matches
that for the frame_order_simulation.py script.
