This UPM module captures a still frame from a Linux V4L device, such
as a USB webcam, and and then allows you to save it as a JPEG image
into a file.

The camera and driver in use must support streaming, mmap-able buffers
and must provide data in YUYV format.  This should encompass most
video cameras out there.  It has been tested with a few off the shelf
USB cameras without any problems.
