find bases based on min_dex, not center_dex
also do the compass search starting from min_dex
reformatted find_bases print statements
when a node spawns another node, it adopts the first node time_search
and basis vectors
only run for specified number of samples
ricochet in opposite direction as well
only do bases every 10 Coulomb searches;
only assess node for convergence if find_bases or ricochet_search was called
make that more elegant
