## transmission_interface

```
* Add developer documentation.
* Build script fixes.
  - Add missing libraries to catkin_package call.
  - Gate tests with CATKIN_ENABLE_TESTING.
  - Add missing files to install target.
* Fix possible memory corruption in tests.
* Perform sanity checks on members, not parameters.
  - The result is the same, but this is more uniform with the rest of the code.
* Enable joint reduction spec for 4-bar linkages.
  - As in the differential transmission, it's convenient to specify an additional
  mechanical reduction on the joint output. This is especially convenient for
  flipping the rotation direction of a joint (negative reduction value).
  - Update URDF loader.
  - Update documentation and tests.
* Trivial, cosmetic fixes.
* C++11 compatibility fixes.
* Fix resource check for multi-dof transmisisons.
* Efficiency fix.
  - cppcheck flagged a [passedByValue] warning. Using const references instead.
* Fix compiler warning.
* Fix license header in some files.
* Test transmission handle duplication.
* Use less pointers in transmission loader data.
  - Only RobotHW and RobotTransmission instances are pointers as they are owned
  by the robot hardware abstraction. The rest are plain members whose lifetime
  is bound to the loader struct.
* Trivial test addition.
* Remove unnecessary header dependencies.
* Catkin fixes.
* Fix bug when adding multiple transmissions.
  - std::vectors were being used to store raw joint data, and when new transmissions
  were added, push_back()s would (potentially) reallocate the vectors and
  invalidate already stored pointers in hardware_interfaces. We now use std::map.
  - Move plugin implementations to a separate library.
  - Export link libraries to the outside.
  - More complete tests.
* Log message change.
* Test greceful error-out with unsupported features.
* Add four-bar-linkage transmission parser.
* Add differential drive transmission parser.
* Move common XML parsing code to TransmissionLoader
  Mechanical reductions, offsets and roles are used by many transmission types.
  The TransmissionLoader base class exposes convenience methods for parsing these
  elements.
* Remove dead code.
* Update loader test, better log statements.
* First draft of transmission loading.
  - Only simple transmission type currently supported.
  - Can load forward map for act->jnt state and jnt->act pos,vel.eff commands.
  - Partial testing.
* Add class for holding transmission interfaces.
  - Mirrors hardware_interface::RobotHW, but for transmissions.
* Allow multiple hw interfaces, Fix #112 <https://github.com/ros-controls/ros_control/issues/112>, and test.
  - Allow to specify multiple hardware interfaces for joints and actuators.
  - Fix invalid xml_element tag. Contents are now stored as a string.
  - Unit test parser.
* Remove rosbuild artifacts. Fix #154 <https://github.com/ros-controls/ros_control/issues/154>.
