Fix for the function name in the lib.dispersion.ns_r1rho_2site module and removed misplaced copyrights.

Added the 'NS R1rho 2-site' R1rho calculating function to the relax library.

This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.

This code originates from the Skrynikov & Tollinger code (the sim_all.tar file
https://gna.org/support/download.php?file_id=18404 attached to https://gna.org/task/?7712#comment5).
Specifically the funNumrho.m file.

This commit follows step 3 of the relaxation dispersion model addition tutorial
(http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

Added the 'NS R1rho 2-site' model to the relax_disp.select_model user function frontend.

This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.

Added the 'NS R1rho 2-site' model to the specific_analyses.relax_disp.variables module.

This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.

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

Renamed all of the current numeric dispersion models in relax to be specific to CPMG-type data.

This is in preparation for adding R1rho numeric models. It was proposed at
http://thread.gmane.org/gmane.science.nmr.relax.devel/4461.

Fixes for the r1rho_on_res_m61.py system test script.

The spins are now different residues. This fixes two system tests.

Fixes for the DPL94 model to make it truly off-resonance.

The tilt angles and R1 data are now used by the target function.

Updated the Relax_disp.test_r1rho_on_res_fixed_time_dpl94 system test for off-resonance data.

The offsets, R1 data, and chemical shifts are now setup or read by the script.

Added an R1 data file to r1rho_on_res_m61, by copying from the r1rho_off_res_tp02 test suite data.

Updated the r1rho_on_res_m61 dispersion on-resonance data for off-resonance models.

The chemical shifts are now the same for all spins, to force perfect on-resonance, and the two spins
are now different residues.
