modifying assemble_kinect's CMakeLists s.t. it no longer clobbers shared_autonomy_msgs. I'm still confused on when to include a package in the find_package(catkign REQUIRED COMPONENTS ...) vs. when it only goes in the catkin_package(CATKIN_DEPENDS...)
adding ipython notebook that tests the assemble_kinect node
modifying the shared_autonomy_msgs catkin files to actually build the actionlib messages
ben_segmentation now compiles to a node that implements an actionlib server.
run_segmentation script in clear_table now talks correctly to assemble_kinect and ben_segmentation
modified actionlib message for requesting segmentation - now gives rgb and depth images, and expects a mask back
