catkin build dependency not listed?

[fjandrad]

Hi it might have been obvious and not required but following instructions step by step I found that I was laking catkin-pkg to run
sudo python setup.py install

Should we add this to the dependencies?
sudo apt-get install python-catkin-pkg

You are correct. Catkin used not to be necessary, but some months ago (I guess around February 2017, see b2d755e) the urdf_parser_py changed the default branch of the repo from master to indigo-devel without any announcement. I now think that the master branch is not maintained (see ros/urdf_parser_py#24) so I guess we should simply require catkin to be installed in the system. Installing catkin should be straightforward also on Windows, as it is available at a pip package (https://pypi.python.org/pypi/catkin_pkg/).
Let's keep this issue open until we fix the docs.
cc @fiorisi because this may affect used of the tool in Windows.

I think that we can close this issue. See 6afa4eb.
