python dynamically setup ros environment

[asmodehn]

When working on a python package, I usually do not assume anything in the environment.
Software is after all generic and abstract, and the environment should, ideally, not matter.
Afterall a python script can easily check and adapt the environment, so that it can do its job.

I m currently working on a package that dynamically setup ROS environment : https://github.com/asmodehn/pyros-setup.

Basically replacing the "source .../setup.bash" call by a python function call, so that ROS can be easily "activated / deactivated" from python code.

It s currently very basic, and there is probably a better/simpler way of doing it ( like calling the _setup_util.py from the workspaces we want to use pyros-dev/pyros-setup#10).
It would be useful to have somewhere...

That looks potentially interesting. How about submitting a PR to add documentation for (or at least a pointer to) it to the top-level README.md in this repo?
