Let's add a bit of documentation

[christophfroehlich]

• The very first line in the readme of the ros2-master branch points to non-ROS 2 docs
• Maybe add/link some demos as proposed in Example tutorial for Pid #70. I know that one can use the tests to figure out how to use the functions, but that's not very userfriendly imho ;)

What do you think?

Absolutely! I wonder if we could also hook control_toolbox into the control.ros.org doxygen generation

[christophfroehlich]

Yeah, why not. But maybe it's more important to have some high-level human-readable docs on control.ros.org than the API. The latter one is not that easy to find, and I never found something relevant via google but only ROS 1-related on http://docs.ros.org. Probably we should cross-link https://control.ros.org/master/doc/api/ more often.

Will be added with ros-controls/control.ros.org#278
