Output video duration after read

This example shows how to automatically retrieve several information data regarding a loaded video on jit.qt.movie. In this case we are taking advance of the message read filename 1 that is output on the second outlet after a successful file load, and using that to trigger several get messages which will also be output out the second outlet and then routed to their proper place using the route object. Additionally, we also implemented a way to quickly scrub through the file using a midi continuous controller via the ctlin object.
