Aside from cleanup, the main change is that instead of using vlc to

transcode a motion jpeg into mpeg (very CPU intensive), I know know
how to alter the camera frame rate on the fly using a wget call. The
downside is that this affects the camera globally (mpeg rate), but
thats okay since the grabwebcams script only allows itself to be run
once at a time to avoid conflict.

Still not hooked into experiment path; waiting for terrabytes of disk
storage!
