This looks good to me. Simple getters added.
VOTE +1.
@pietermartin --- you are really introspecting deep into the traversal.
Note that we have yet to publish the virtual machine step library and thus,
things like `LoopTraversal` may not be in the specification. Thus, we can't
guarantee you stability of the API in this area. Just a heads up.
