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.
