[ros-users] New rosjava Client Library

[Juan Antonio Breña Moral]

Good night Ken,

with your note, the example runs nice.

Lorentz, in previous implementation, had very useful example to learn 
concepts about services with rosjava:

AddTwoIntsServer.java
AddTwoIntsClient.java

I think that we could add them to the set of samples. This weekend I 
will scratch the library to try to port to the new implementation.

Cheers.

Juan Antonio
