The 'CR72' and 'MMQ CR72' models are now classified as nested in the dispersion auto-analysis.

The grid search for the 'MMQ CR72' model will therefore be skipped and the parameters taken from the
'CR72' model. This will however rarely, if ever, be used.

Updated more test suite scripts to call the relax_disp.cpmg_frq user function.

Updated two dispersion scripts in the test data directories to work with the current design.

Fixes for the relax_disp.plot_disp_curves user function - the colours behaviour is now back to normal.

This does not affect relax 3.1.0 and is only a recent bug.

Fix for the previous commit (r21857).

Introduced the eliminate argument for the dispersion auto-analysis.

This flag allows model and Monte Carlo simulation elimination to be deactivated.

Increased the size of the grid search in the Relax_disp.test_m61_exp_data_to_m61 system test.

This should increase the stability of this test.

Changed some warnings in the dispersion analysis so they only show if R1rho data is loaded.

This is for missing chemical shifts and R1 data.

Fixes for bugs recently introduced to the relax_disp.nessy_input user function.

This was only a few commits ago so it doesn't affect relax 3.1.0.

Improvements for the find_intensity_keys() dispersion analysis function.

This now handles the reference point None being converted to NaN in numpy arrays and the logic is
now clearer.
