Tooling to build ROS indigo and custom packages using the Buck build system. The ROS distribution is built by invoking catkin build within a Buck genrule. Once the upstream ROS packages are built, headers are libraries are available to buck binaries just like any other system dependency. This allows us to re-use all the CMakeLists.txt for upstream ROS code, while using Buck for all custom code.

Builds roscpp and a simple node that's able to connect to the rosmaster.
