Behavior Tree in Editor

This is experimental. A Behavior tree implemetation enables a conditional call for an action node. If conditions are not satisfied for a button, the associated action to the button will not be executed when user clicks it

editor/controller/BTree/selectors.tree

BTree calls BThandler when actionNode is activated. The parameters are stored in backboard.
