        jQuery Plugin textGrow (leftlogic.com/info/articles/auto_grow_text)
        (c) 2006 Remy Sharp (leftlogic.com)

        Usage: jQuery('input').textGrow({ pad: 25 });
            - pad: trailing padding in pixels - default 25px
            - min_width: minimum width of the text box in pixels
            - max_width: maximum width of the text box in pixels

        If min and max width are not passed in, you can apply this
        via CSS using min-width and max-width attributes.

        See example at: leftlogic.com/info/articles/auto_grow_text
