Cleanup (removed an unused function) and gpgga_msg.time_recv is now correctly updated
transverse_mercator: Added the original C++ version of the library
Added gpgga_to_tranmerc component. This will eventually replace the gpgga_to_utm component which has several limitations.
pose_2d_estimator: First alpha release, simulator and ros node wrapper both use the same library, yaw angle is not yet fully implemented.
pose_2d_estimator: Forgot to delete the autogenerated sample data...!
