More spacing before the sectioning printouts in the relaxation dispersion auto-analysis.

Spun out a number of dispersion methods into the new specific_analyses.relax_disp.parameters module.

This is a module of functions relating to the parameters of the relaxation dispersion models.

Updated the backend of the relax_disp.select_model to handle the new model names.

Updated the models in the script for the full relaxation dispersion analysis of Hansen's data.

Created a script for running a full relaxation dispersion analysis on Flemming Hansen's data.

This is located in the shared data directories and is not part of the test suite as a full analysis
will take far too long.

Completed the relaxation dispersion calculate() method.

This allows the R2eff/R1rho values to be calculated for the fixed relaxation time period
experiments through the calc user function.

Fixes for some latent bugs in the specific_analyses.relax_disp.disp_data module.

The checks for the CPMG-data type in a number of functions now uses the CPMG_EXP list instead of
fixed strings.

Improvements to the specific_analysis.relax_disp.disp_data module.

The function loop_all_data() has been expanded to include the relaxation time period into the loop.
The functions return_intensity() and return_key() have been added to return peak intensities and the
key corresponding to the data returned by loop_all_data().

Created the lib.dispersion.calc_two_point_r2eff() function.

This is for calculating the R2eff/R1rho value for the fixed relaxation time data.

Typo fix in the new loop_all_data() function.
