    feedback - the selector for the element that gives the user feedback. Note that this will be relative to the form the plugin is run against.
    hardLimit - whether to stop the user being able to keep adding characters. Defaults to true.
    useInput - whether to look for a hidden input named 'maxlength' instead of the maxlength attribute. Defaults to false.
    words - limit by characters or words, set this to true to limit by words. Defaults to false.
