simple standalone example showing how to stuff an Image.msg and publish to ROS #3

There are many ways to improve this little program and make it more general, such as using the ROS CV Bridge, but there is some value in showing just how simple it is to take images from some other framework (in this case, OpenCV), manually populate the sensor_msgs::Image fields, and publish messages to ROS. All using a standalone Makefile, thanks to the pkg-config files from the ROS packages.
