Addressing user issue #209. Our quick_setup guide was still recommending users check out v.0.2.0 of our packages. Removed the reference to a specific package version and instead included a note that users can explicitly declare a package version if desired.
Tested by making the change locally in the package manifest.
* added example of implementing a UnityService
* adding tutorial for unity service
* added a couple comments to the example code
* typos and code standard fixes
* consistency: changing the service name for position_service to pos_srv
* updating the tutorial to match the corresponding script
Pick and place tutorial was failing to compile its scripts because
the package manifest was pointing to an older version of
ROS-TCP-Connector. Updated the manifest and also pulled latest changes
for ros_tcp_endpoint.
Tested by running DemoScene
