Proposes a move in state space.
This operator changes a beast.tree.
As sub-tree slide but with Bactrian kernel to determine size of step. Moves the height of an internal node along the branch. If it moves up, it can exceed the root and become a new root. If it moves down, it may need to make a choice which branch to slide down into.
