programmatic access for power users

[zackgalbreath]

A common question during the hackathon was "is there an API to interact with arbor?" Apparently power users prefer to use the keyboard as opposed to the mouse. This issue mostly came up when discussing the possibility of batch processing (performing the same workflow on many different inputs).

Another related request / potential solution was the ability to download a whole workflow as a standalone script for offline use. I could see this working as long as the workflow doesn't swap back and forth between languages.
