Revision cad1ab0c
Created ROS skeleton for Headlights node. Currently has functionality for getting headlights set via a message and setting some variables to the message contents, but doesn't write to hardware. Also does not include code in libscout to support headlights yet.
Also, I haven't tried compiling this, but I didn't see any syntax errors. I'll compile it when I have a working ROS install.

If your codebase is fairly large or has different sets of APIs, you |

should use the doxygen 'group' tag to keep these APIs together. For |

example, the roscpp documentation has 'libros' group. |
