Added systemtest Relax_disp.test_r1rho_kjaergaard_auto_check_graphs, to check that the contents of all combinations of graphs are consistent.
The systemtest actual show that the error is changing per run-through.
This is a bug, which should be corrected.
sr #3124(https://gna.org/support/?3124): Grace graphs production for R1rho analysis with R2_eff as function of Omega_eff.
sr #3138(https://gna.org/support/?3138): Interpolating theta through spin-lock offset [Omega], rather than spin-lock field strength [w1].
