The r1_fit flag is stored in the Disp_minimise_command class and passed into the target function.

This matches the details at http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6736.

The specific_analyses.relax_disp.optimisation.Disp_minimise_command class calls is_r1_optimised()
and stores the result. This is then passed into the relaxation dispersion target function class.

Fix for the misspelled is_r1_optimised() function.

Copying the R2eff value from the reading of R2eff results in the auto analyses of relax_disp.

Implemented to the front_end of the value.copy, a "force" flag to overwrite destination value.

Implemented to the back_end of the value.copy, a "force" flag to overwrite destination value.

Revert of commit r25002 in branches/R1_fitting.

This was not the correct implementation, since copying of 'R2eff' is
not really a "parameter", which can be "fitted" in the sence of the dispersion models.

Rather, R2eff should be copied, with value.copy() function.

Spelling fix for the is_r1_optimised() function name.

Implemented the specific_analyses.relax_disp.parameters.r1_setup() function.

This matches the description at http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6739
and http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6736.

Implemented the very basic relax_disp.r1_fit user function.

This is as discussed at http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6737.

Created the specific_analyses.relax_disp.data.is_r1_optimsed() function.

This follows from an idea for handling R1 optimisation in the tread at
http://thread.gmane.org/gmane.science.nmr.relax.scm/22850/focus=6736.

This relaxation dispersion function can be used anywhere that requires the knowledge that R1 values
should be fitted during optimisation or if loaded values should be used.
