Event library for handling events for eidos
From http://docs.python-requests.org/en/latest/user/install/?highlight=gevent
If you are using the requests.async module for making concurrent requests, you need to install gevent.
For OSX and Ubuntu, to install gevent, you’ll need libevent.
OSX:
$ brew install libevent
Ubuntu:
$ apt-get install libevent-dev
Once you have libevent, you can install gevent with pip:
$ pip install gevent
For Windows, you don't need libevent, but you would need to use installer for the libraries. You can find both the gevent library library from http://www.lfd.uci.edu/~gohlke/pythonlibs/. Install them and copy the library over into virtual environment
