DESCRIPTION
    This library provides a more interactive textarea widget, which resize
    on the fly as user's typing. The only usage is as in synopsis, just call
    the constructor with one proper parameter hash. Valid configuration keys
    and values are described below.

CONFIGUARTIONS
    The constructor takes only one hash variable. Valid keys and its
    description enlisted below:

    elementId
        Necessary. In your HTML, there must be an existing textarea with an
        ID. The element ID must be given here, otherwise this library simply
        just can't work.

    inScreen
        Optional, default to false. This option allows you to prevent the
        editing textarea from growing bigger then screen. Once set to true,
        a scroll bar will show up when it's about to grow bigger then
        screen.

    resizeStep
        Optional, default to 100. This option decides the resize step upon
        each grow or shrink. Setting larger value could help preventing from
        resizing too often.
