This new release features the new method TrajectoryGenerator.generateRotationTank, which generates a trajectory that rotates in place for a tank drive robot. The Trajectory Visualization Tool has also been improved; it now uses JSON instead of CSV for saving configuration data. Legacy support for CSV is still kept. Finally, TankDriveTrajectory now has a new method isSmooth, which tells you if the wheels ever reverse direction because of a tight turn in this trajectory.
v2.2.0 some issues with Moment.getFacingAbsolute() and Moment.getFacingRelative() and the trajectory mirroring methods.
