Retired (deleted) unused packages.
Moved their msg/srv definitions to the messages/ package instead, and revised the libscout and scoutsim files that depended on those namespaces.
Fixed Odometry behavior so that it now works and then added a get readings functionality to sonarcontrol.
Updated ButtonControl and SonarControl.
Finally, the behavior compiles. Had to fix a lot of problems involving misunderstandings with Publisher/Client/ServiceServer/ServiceClient confusion.
We can now run priya_behavior as an executable, though the process for generating behavior executables still needs some work.
Updated the licensing information in many files.
This is a broken commit because I decided to do this at a bad time. Sorry! The build will be working after next commit, I promise (and I won't push till then). This commit reflects the licensing in the files after I used my auto-add/remove script.
Chaned libscout sonar code so that it turned sonar on and off when necessary.
Integrated SonarControl into the libscout package.
Created SonarControl files. Not tested and therefore not included in libscout interface yet.
