Bug fix for the frame order grid_search() method - the point grid is now properly constructed.

Bug fix for the frame order grid search - the non-linear grid search is now performed.

Previously the minfx.grid.grid() function was being used, causing the custom grid to be ignored.
Now minfx.grid.grid_point_array() is being used allowing the non-regular grid to be used.

Fix for the frame order grid_search() method - the pseudo-elliptic parameters were incorrectly named.

Created the func_pseudo_ellipse() optimisation target fn. for the pseudo-elliptic cone model.

The structure of the Frame_order class has been simplified for handling multiple frame order models.

Modified compile_2nd_matrix_pseudo_ellipse() to rotate and return the frame order matrix.

Alphabetical arrangement of the functions in the frame_order_matrix_ops module.

Removed the docstring linewrapping in the frame order maths_fns module.

Added support for the pseudo-elliptic cone model in the frame order user function and specific code.

Clean up of the maths functions in part_int_daeg2_pseudo_ellipse_xy().

Added a debugging print out to test_compile_2nd_matrix_pseudo_ellipse().
