    Make generic calls to RCE API.

    To call any API method, instanciate the API with the URL of your
    RCE instance and your user token.
    Then use a method call with the name of your API method, and pass the
    correct parameters.

    Will return a dict with the response from the API call

    eg.:
    api = RhodeCodeAPI('http://my.rhodecode.com');
