Renamed the lib.frame_order.rotor_axis module to lib.frame_order.conversions.

This module will be used for all sorts of frame order parameter conversions.

Created the lib.frame_order.rotor_axis.convert_axis_alpha_to_spherical() function.

This will convert the axis alpha angle to the equivalent spherical angles theta and phi.

Skip production of plotting r1rho r2 as function of effective field w_eff, when spin.isotope is not present.

This can happen when it is 'exp_fit' model curve fitting.

sr #3124(https://gna.org/support/?3124): Grace graphs production for R1rho analysis with R2_eff as function of Omega_eff.
sr #3138(https://gna.org/support/?3138): Interpolating theta through spin-lock offset [Omega], rather than spin-lock field strength [w1].

Replaced repeated calculation of rotating frame parameters to use function in lib/nmr.py.

sr #3138(https://gna.org/support/?3138): Interpolating theta through spin-lock offset [Omega], rather than spin-lock field strength [w1].

Added function to calculate rotating frame paramters for lib/nmr.py.

This function is called several times in specific_analyses/relax_disp/data.py by plotting functions.

Deleted the ancient optimisation_testing.py script, as this no longer works and is of no use.

Some Python 3 fixes as identified by the 2to3 script.
........

Fixes for the CaM free-rotor pseudo-ellipse frame order model test data set.

This is for the constraint 0 <= theta_x <= theta_y <= pi, as the old data was created with theta_x
> theta_y. The new data is also of high quality using 20 million structures and numpy.float128 data
averaging.

Renamed the other function to represent the functionality of returning data in correct xmgrace form.

Also improved the epydoc information, for the return of values.

Corrected the epydoc information for the return_offset_data() function in specific_analyses.relax_disp.data.

The function has been extended to return more data.
