removed plot-call creation. formatted new return from translator.

@etpinard, here are the changes we need. I need to change a reference from 'nodejs' to 'node' on the translator in streambed. but other than that, this *should* give us what we need.
call the translator *again* to get the execution code. this is a little overkill... but the alternative, as it's setup now, is pretty ugly. most of the issue here concerns adding the `fileopt='overwrite'` properly for *each* different language. Either removing/inserting this into a code-string is a pretty hack-y approach.
