        Add a custom classifier.

        The parameter `cls_type' can assume the values

                html
                js
                vbs
                url
                text
                sample
                image

        and defines the custom classifier scope.

        The parameter `method' is the method (not its name) to be additionaly invoked.
        The method parameters depend on the `cls_type' value and are listed here for
        convenience

                html    method(url, html)
                js      method(url, script)
                vbs     method(url, script)
                url     method(url)
                text    method(url, text)
                sample  method(sample, md5)
                image   method(url, text)

        @param cls_type: Classifier type
        @param cls_type: C{str}
        @param method: Classifier method
        @param method: method
