Looks very interesting! Thanks for supplying detailed documentation.

A major gap in the existing ROS localization solution (robot_pose_ekf) has
been with respect to periodic absolute measurements, especially GPS fixes
and data from mocap systems. Does robot_localization handle these cases at
all, or provide for them to be handled with further development?

Thanks again for contributing this,

Mike
