             *
             * For example, let's assume we have five total input structures, and are only searching for one ion.  Let's
             * also assume that three of those structures have m/z A and the remaining two have m/z B.  The windows might

             * |----A----|
             *        |----B----|

             * approach.  Similarly, B is assigned a count of 5, as the possibility for collision/confusion is symmetric.
             *
             * Note that this is an over-approximation of collisions, as we could more precisely only consider intersections
             * when the exact m/z of B falls within the window around A and vice versa.  However, because we have observed
             * cases where the MS sensor doesn't report structures at exactly the m/z we predict, we employ this weaker
