Added function to sort models before auto analyses.
They are sorted in order:
exp_type: EXP_TYPE_R2EFF, EXP_TYPE_NOREX, EXP_TYPE_NOREX_R1RHO, EXP_TYPE_CPMG_SQ, EXP_TYPE_CPMG_MMQ, EXP_TYPE_R1RHO
equation: EQ_SILICO, EQ_ANALYTIC, EQ_NUMERIC
Nr of chemical sites: 2 or 3
Year: Newest models first.
Nr of params:
sr #3135(https://gna.org/support/?3135): Optimisation of the R1 relaxation rate for the off-resonance R1rho relaxation dispersion models.
