catvehicle-2.0.0.tgz

An updated and major breaking version of the catvehicle testbed, with the following updates:

• changed the name of the robot (and therefore nearly every topic) to catvehicle, rather than azcar_sim
• updated launch files to permit selective startup of sensors
• additional sensors with some sensor joints permanently renamed
• a single package, rather than a collection of packages in a workspace; therefore it should be extracted into an existing workspace
