NumCosmoMathMSetcmp_all

Compares two NcmMSet objects. It returns 0 if they contain the same models, with the same number of parameters, in the same order. It returns -1 if mset0 has fewer models than mset1, or if they have the same number of models but mset0 has a model with fewer parameters than the corresponding model in mset1. It returns 1 if mset0 has more models than mset1, or if they have the same number of models but mset0 has a model with more parameters than the corresponding model in mset1.
