pose_2d_estimator: Added launch file for generating Armadillo IV simulation data.
differential_odometry: Added optional parameters ticks_per_meter_left and ticks_per_meter_right to support odd encoder outputs. Negative values are supported.
pose_2d_estimator: Changed the minimum distance for estimating the absolute orientation from 0.5 to 0.25 meter to see if this works better.
sdu_weeding_trial: Major cleanup and configuration for Armadillo IV autonomous waypoint navigation, not finished.
sdu_kjen_sandbox: Added support for printing current position using the Wiimote
