The relax_disp.relax_time page is now always shown in the peak intensity wizard for the dispersion GUI.

This number is needed for the fixed time period experiments as well to calculated the R2eff/R1rho
values and errors.

Updated the specific_analyses.relax_disp.variables module for the relax_disp.exp_type changes.

Updated the relax_disp.exp_type user function to be more specific an include more experiment types.

The proper experiment type is now set for the Relax_disp.test_hansen_trunc_data GUI test.

Bug fix for the peak intensity error analysis in the dispersion auto-analysis.

Now the error analysis is split based on the magnetic field strength. Previously the analysis was
a mess with the split often being individual spectra.

Modified the dispersion calculate() method for the R2eff values to use the analytic equation.

For the R2eff/R1rho values calculated for the fixed time period dispersion experiments via the calc
user function, the very slow and tedious bootstrapping approach has been replaced by the very quick
direct error calculation. The two techniques produce the same results as the bootstrap simulation
number approaches infinity.

Updated the LM63 model comparison table.

Converted the readme file for Flemming Hansen's CPMG data directory to uppercase.

Added the ShereKhan results for the high-precision R2eff data for Hansen's CPMG data.

Redesign of the relax_disp.sherekhan_input user function to handle spin clustering.
