Log Message:
New method setStateFunction for TreeMaker.

- Refactor tree method to allow callback function (set with
  setStateFunction) to influence node state.

- hasChildren now stores the result of getChildren in a local cache, which
  getChildren uses and clears on a subsequent call. This was needed to avoid
  generating the children list for open nodes twice.

- hasChildren now flattens its return value to a boolean; tree relies on
  this.
