code: public static void walkEntityTree(final EntityContainer container, final EntityVisitor visitor) {
  	walkEntityTree(container, Integer.MAX_VALUE, visitor);
      }
docs: Walks through all entities (recursive and breadth-first). Walking can be stopped or filtered
  based on the visit result returned.
