Computes an intuitively nice marker ordering using 2-points LOD.


The nicemapl command is invoked as either one of :


The nicemapl command orders the current list of active markers using a simple Nearest Neighbor heuristics. Starting from each marker successively, it builds a map by always selecting the marker with the strongest LOD as the next marker. The best map according to multipoint maximum likelihood is inserted in the heap.

Warning: since 2-points estimations are typically unavailable for some pairs of markers when data-sets are merged, this command will return very poor maps on such merged data. This command should be used preferably to nicemapd when some data-sets have been merged with separate parameter estimation (using mergor).
