Converted the 'MQ CR72' dispersion model to handle MMQ data.

This model can now handle proton-heteronuclear SQ, ZQ, DQ, and MQ CPMG-type data. Some debugging
might still be required.

Bug fix for the 'MMQ 2-site' dispersion model target function.

The relaxation time was being taken as that of the first experiment for all experiments. This is a
relic from the code being copied from a single experiment type model.

The relax_disp.plot_disp_curves now shows the experiment type as part of the Y-axis label.

This is to allow for easy identification of the experiment when more than one is present.

Fixes for the relax_disp.plot_exp_curves user function for the lib.software.grace changes.

Large improvements to the relax_disp.plot_disp_curves user function including MMQ model support.

This user function now handles multiple dispersion data sets better by placing each into a new
graph. All graphs have also been improved by matching the colours of the sets for each field
strength and using different symbols and line styles to emphasize the data.

Improvements to the lib.software.grace module.

The set colours are now applied to all set objects. And the axis label and tick sizes are now much
smaller.

Improved Grace graph scaling and arrangement when multiple graphs are present.

The lib.software.grace.write_xy_data() function now executes the 'autoscale' command for each graph
and executes the 'arrange' to layout the graphs automatically.
