* Fixes for the [http://www.nmr-relax.com/manual/relax_disp_cpmgfit_input.html relax_disp.cpmgfit_input user function] for the [[IT99]] model grid search options.
* Updated the CPMGFit results for the [[IT99]] grid search fixes of the last commit.
* Basic fix for the checks of the [http://www.nmr-relax.com/manual/Relax_disp_test_hansen_cpmgfit_input.html Relax_disp.test_hansen_cpmgfit_input user function]. The 't<sub>ex</sub>' parameter is now set as 'Tau'.
* Disabled the Relax_disp.test_r1rho_on_res_fixed_time_m61b system test as the [[M61b]] model is rubbish. The model cannot be properly optimised as the parameters are not independent of each other.
* Fixes for the dispersion specific code. The Grace graph code of lib.software.grace no longer accepts the axis min and max arguments.
