Chemical exchange relaxation is now handled properly in the relaxation_data() function.

The back-calculated relaxation data is now correct for model-free models with Rex.

Te values of zero can now be handled by the spectral_density_mf_orig() model-free method.

The initial parameters are now slightly perturbed in the 3 tm2 grid system tests.

This allows the optimisation to be a bit challenged.

Reverted revision r12259 as this was completely false - it actually undid the previous commit.

The command used was:
svn merge -r12259:12258 .

This time really turn off the optimisation constraints!

The tm2 model parameters are now properly initialised in the tm2 grid system test script.

Turned constraints off in the tm2 grid system tests to speed up the tests.

Constrained optimisation is not required in these simple models to find the exact solution.

The test_m2_grid_vs_m3() system test should really have been against model m4!

Model m3 has no te parameter, so the model does not fit perfectly.

Fix for the test_tm2_grid system test, the diffusion tensor should not be initialised.

Simplified the 3 system tests based on the model-free tm2 grid by shifting all the code to the script.
