Fixed CW and CCW circle behaviors to turn the right way XD
Added Sensors class that abstracts away sensors from behaviors. Stops creatingduplicated sensors for each scout.
Added initial GUI for testing, renamed cw and ccw behaviors
Temporary, possibly broken, commit to add EncodersControl.
Sorry - my ros build is broken. I will immediately debug on Priya's machine.
New behavior implementation that uses a list of behaviors to command multiple scouts with multiple behaviors.
