n_iph_fast_cest: new experiment that performs pure in-phase N15 CEST assuming that all magnetization perpendicular to the effective B1 field is dephased. (This is much faster than the way where several propagators are calculated to simulate B1 inhomogeneity.)
"filter" module: each data point object now has the possibility to implement a "filter" function that basically decides whether the point should be considered in the calculation or not.
"on_resonance_filter" experimental parameter in "n_iph_fast_cest" type define a zone around the major state resonance where points should be filtered out. Could be useful for example when time_t1 is small and the magnetization perpendicular to the effective B1 is not fully dephased.
