First attempt at catkinizing... seems good, but slightly untested
Updated CMakeLists.txt to automatically build messages from skeletonmsgs_nu, and
removed documentation file
This file had a slightly incorrect dependency.
Added the heartbeat message and it builds. Adding now to baxter_controller.py
Merge branch 'heartbeat_msg' of https://github.com/adb421/skeletontracker_nu into heartbeat_msg

Conflicts:
	src/skeletontracker_nu.cpp
Fixed some small bugs while testing should work now.
