[cwru] Updates to Sonar, Data Storage

A new data storage technique has been implemented. Every scan is
processed into a "RobotBite" (think byte). It stores as much information
as possible as can be directly calculated from the scan of another robot
(time, x, y, speed, heading, etc.). The Sonar storage technique is also
being refined. Once implemented, the next step is to get the other
brains reading that structure (ex. Projector 1st, then other brains).
