 * The HookBuilder constructor is given the $transitions service and a Transition instance.  Thus, a HookBuilder
 * instance may only be used for one specific Transition object. (side note: the _treeChanges accessor is private
 * in the Transition class, so we must also provide the Transition's _treeChanges)
