Created a Grace graph for the 1H SQ data fitting of cpmg_fit.

Fixes for the cpmg_fit results for all of the data from Korzhnev et al., 2005.

The dwH value must start negative, otherwise optimisation will fail to find the correct minimum!

Created a Grace plot of the failed cpmg_fit results.

This is for the Korzhnev et al., 2005 data, using all data sets.

Shifted the relax results for the 15N SQ Korzhnev 2005 CPMG data to its own directory.

The relax save state and grace curve have been added to the repository as well.

Updated the cpmg_fit results for all Korzhnev et al., 2005 data.

Added the cpmg_fit results for optimisation all of the Korzhnev et al., 2005 CPMG data.

This is for the 2-site model. It includes all proton-nitrogen SQ, ZQ, DQ, and MQ data.

Reintroduced the F vector into r2eff_mmq_2site_mq() to calculate the magnetisation.

Updated the Relax_disp.test_korzhnev_2005_15n_zq_data system test.

It now starts at the relax solution and the test passes as it seems to reasonably match the cpmg_fit
results.

The cpmg_fit script for the Korzhnev et al., 2005 15N ZQ CPMG data now starts at the relax solution.

This is to try to find better solutions for dw and dwH, thought it was not so successful.

Created 5 more system tests for checking the optimisation of single sets of Korzhnev et al., 2005 data.

These are Relax_disp.test_korzhnev_2005_15n_dq_data, Relax_disp.test_korzhnev_2005_15n_mq_data,
Relax_disp.test_korzhnev_2005_15n_zq_data, Relax_disp.test_korzhnev_2005_1h_mq_data, and
Relax_disp.test_korzhnev_2005_1h_sq_data. These should individually test out all parts of the
'MMQ 2-site' dispersion model.
