catkin-ize libsweep

[sevenbitbyte]

If you wrap the libsweep library in a catkin package(it could be a standalone git repo) you can remove the manual compile and install steps and only install it locally in the ROS workspace rather than system wide. This is especially useful to systems integrators as it streamlines image creation.

@sevenbitbyte, this sounds like a good idea to me! Will test this out, thanks!
