config of proposed configurations, using
the single zone information in overlap, see if each proposed configuration
is valid in that the single zones don't overlap with each other.check_overlap(config, overlap)n by k matrix of configurations where n is
the number of proposed configurations and k is the configuration size
(in terms of the number of single zones)n indicating if each of the proposed configs
overlap (0 if they do overlap, 1 if they don't)}
