[ros-users] rosjava test

I'll take a look at how to add Java JUnit testing to the rosbuild cmake
files first.  Whether I get it to work or not, I'll let you know how it

As for rostest, I had seen this, but I noticed that it is for C++ and Python
only.  Once I get CMake JUnit testing  to work the rostest should be fairly
straight forward.
