2.2.0 (2015-05-22)
------------------
* Added tf2-friendly tf_prefix appending
* Corrected for IMU orientation in navsat_transform
* Fixed issue with out-of-order measurements and pose resets
* Nodes now assume ENU standard for yaw data
* Removed gps_common dependency
* Adding option to navsat_transform_node that enables the use of the heading from the odometry message instead of an IMU.
* Changed frame_id used in setPoseCallback to be the world_frame
* Optimized Eigen arithmetic for signficiant performance boost
* Migrated to tf2
* Code refactoring and reorganization
* Removed roll and pitch from navsat_transform calculations
* Fixed transform for IMU data to better support mounting IMUs in non-standard orientations
* Added feature to navsat_transform_node whereby filtered odometry data can be coverted back into navsat data
* Added a parameter to allow future dating the world_frame->base_link_frame transform.<commit_msg>Updating changelong prior to 2.2.1<commit_after>^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
