was in a massive 'im so lost'-codehole. I clawed my way out of it -- like a mountaineer summitting a small hill. Traverser.path(label) and Traverser.sideEffect(label) now exist to denote the distinction. No more Traverser.get(). Moreover, sideEffects are no longer updated with path information. Led to so many confusiing situation. Fixed #316 --- for @dkuppitz with love. Also, @dkuppitz, lets review the Traverser API sometime and see what we think.
