Subject: Add driver dependencies to setup.py, and document how to install
 this.

This should address Issue 5 (theoretically some of the dependencies are
OS-specific but that's a longer problem).

Also partially addresses Issue 9 because now we have an easy to understand
"install and try out" option.

+## Example Usage
+
+Most of the drivers require optional dependencies, and those are listed in the
+table below. If you do not want to install the dependencies manually, you should
+be able to set this up using `virtualenv` and `pip`:
+
+```shell
+$ python3 -m venv $(pwd)/glucometerutils-venv
+$ . glucometerutils-venv/bin/activate
+(glucometerutils-venv) $ DRIVER=myglucometer-driver  # see table below
+(glucometerutils-venv) $ pip install git+https://github.com/Flameeyes/glucometerutils.git#egg=project[${DRIVER}]
+(glucometerutils-venv) $ glucometer --driver ${DRIVER} help
