Fix for the specific_analyses.relax_disp.disp_data.return_value_from_frq_index() function.

This cdp.spectrometer_frq_list list structure rather than the cdp.spectrometer_frq dictionary should
be used.

Small simplification of the lib.dispersion.m61b module.

Created the Relax_disp.test_r1rho_on_res_fixed_time_m61b system test.

This is for the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).

This commit follows step 7 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Properly added the Sparky peak list (this should have been the commit of r19982).

Reverted the last commit (r19982) as too much was committed.

The command used was:
svn merge -r19982:19981 .

Added the Sparky peak lists which should have been committed in r19980.

Missing import of the MODEL_M61B variable.

Created test data for the 'M61 skew' R1rho model.

This is the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).

This commit follows step 7 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Renamed the r1rho_on_res dispersion test suite data directory to r1rho_on_res_m61.

Renamed the lib.dispersion.equations module to lib.dispersion.two_point.
