simple mean |F|n target
This class implements the target function for calculating mean |F|n as a function of position in reciprocal space. It includes the appropriate multiplicity correction, and so can be applied to any type with an 'f' member with the same dimensions as an |F| or |U| (or an uncorrected |E|).
This function should not be used to scale F's to E's. See TargetFn_scaleEsq.
