differential_odometry: Added support for absolute encoder values. Fixed a minor bug regarding updating.
Working on the pose_2d_estimator, not finished yet!
transverse_mercator: removed a seemingly unnecessary subdir in src.
Update to MarkerLocator
Merge remote-tracking branch 'upstream/master'
pose_2d_estimator: The simulation part works though the preprocessor class needs some work. A bug was removed from the cleanup script.
