The CR72 dispersion model descriptions now emphasise the fact that it is not accurate on all time scales.

This is for the dispersion chapter of the user manual.

Fix for the LM63 dispersion model equation in the manual.

Added the new relax IT99 model results to the software_comparison file.

This is for the truncated CPMG data from Flemming Hansen.

Updated all of the relax results for the IT99 model fix.

Bug fix for the Ishima and Torchia 1999 dispersion model.

Their value of omega_1eff is defined in terms of nu_CPMG, hence it is missing the radian unit. This
is clearly a mistake, but is probably compensated by their stated rather than derived definitions.

Updated all of the results for the truncated CPMG data from Flemming Hansen in the test suite.

The results are now different as the errors are now much more precise as they come from all spin
systems rather than just the truncated set of :4, :70, and :71.

Fix for the relax_disp.sherekhan_input user function for the changes of r21513.

Bug fix for the relax_disp.cpmgfit_input user function.

The nu_CPMG values need to be doubled and then divided by 1e3 to obtain the 1/tau_CPMG values in ms.

Another change of the base relax files of the truncated CPMG data.

Changed the current data pipe in the relax saved states for Flemming Hansen's truncated CPMG data.
