Laurent Rineau fc3061c822 Bug fix: fix AABB_tree doc and code about preconditions !empty() ... The AABB_tree code had several assertions checkinng that the tree was not empty. Those preconditions were not documented. There was several places in the code were it was not really required that the tree is not empty. This patch rationalizes the preconditions: only the function `bbox()` and the queries about distances or closest things now require that the tree is not empty.		2013-01-15 17:19:11 +01:00
