Add short paragraph on "atomic weighting" to theory documentation
As pointed out by @EsmeeBerger , we should probably add a short paragraph on "atomic weighting" to the theory documentation.
For example some equation along the lines of
F_{coh} = \sum_i \sum_j w_i w_j \exp(-iq (r_i - r_j))
where w_i
are the coherent weights in the Weights
class.
