OpenVideo for FRC Vision Processing

This library uses OpenCV and LIBUVC to open a usb connected camera, lowers its exposure, and returns the camera stream. FRC Vision targets use retroreflective tape, which reflects light in the direction it came from. A camera's exposure determines how much light is let in. By lowering the exposure on this camera, the vision targets in the image are more visible.
