Created the Relax_disp.test_r1rho_on_res_fixed_time_dpl94 system test.

This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.

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

Added support for the DPL94 model to the relax_disp.select_model user function back end.

This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.

(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Created the DPL94 model target function.

This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.

This commit follows step 4 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Added the DPL94 model equations to the relax library.

This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.

(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Updates to the Relax_disp.test_r1rho_on_res_fixed_time_m61b system test.

Added the 'DPL94' model to the relax_disp.select_model user function frontend.

This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.

This commit follows step 2 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Added the 'DPL94' model to the specific_analyses.relax_disp.variables module.

This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.

This commit follows step 1 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Completed the lib.dispersion.m61.r1rho_M61() function.

Now the R1 relaxation rate and rotating frame tilt angle are correctly handled. This is not used in
the target functions as support for the R1 and offset is not yet implemented.

Small changes to the r1rho_on_res_m61b dispersion test data.

One R20 rate has been increased.

Fixes for the func_M61b() dispersion target function.

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