Added 'process_doc' optional parameter. Closes #7.
Added 'process_doc' optional parameter. Closes #7.

Now you can write docs in Markdown or reStructured Text and
give swagger a function to process docstrings. It could
look like that:

```python
import flask_swagger
import CommonMark

def process_doc(text):
    parser = CommonMark.DocParser()
    renderer = CommonMark.HTMLRenderer()
    ast = parser.parse(text)
    return renderer.render(ast)

@app.route("/docs/swagger.json")
def swagger_spec():
    spec = flask_swagger.swagger(app, process_doc=process_doc)
    return jsonify(spec)
```
