Looking at the code, it seems that axe.run() takes arguments as strings representing Javascript objects:

https://github.com/mozilla-services/axe-selenium-python/blob/270c8cd5aed76e31d8c9086e397a487126425026/axe_selenium_python/axe.py#L36-L52

This is a surprising interface for a Python object, and I can't find it documented anywhere, or exercised in the unit test. What is the correct way of specifying Axe the following options?

{"runOnly": {"type": "tag", "value": ["wcaga2a"]}}

Maybe you need:

• an example to show the correct way to call the function
• if the objects are not strings then json.dumps() them

or maybe I'm reading all wrong?
