weighted_matrix_array

Internal helper used by <code>compute_matrix()</code> and <code>contact_matrix()</code> to
turn a merged contacts table into the rank-<code>2K</code>
array of weighted contact counts. Each grouping contributes a
participant-side and a contact-side axis, in that order across the two
halves of the array.
