% Generate the ds.bestbin structure used by dispres_discpatch,
% or append additional patches to an existing one.
% detsimple is a list of detections to include in the display.
% batchidx is just an identifier of the batch number, used to
% separate different batches in the final display.  npatchesper
% is an upper bound on the number of patches included for each
% detector.  ranks specifies the ranks of the detections displayed.
