Following function is required to initialise Reveal
The function is called in the following manner :

        Parameter description :
        type        ->        0 for vertical | 1 for horizantal
        div1bg        ->        Background color of first layer                (eg. '#CCCCCC')
        div2bg        ->        Background color of second layer        (eg. '#CCCCCC')
        div1bw        ->        Border width of first layer                (eg. 1)
        div2bw        ->        Border width of second layer                (eg. 1)
        div1bc        ->        Border color of first layer                (eg. '#000000')
        div2bc        ->        Border color of second layer                (eg. '#000000')
        step        ->        The amount revealed every interval        (eg. 5)
        timeOut        ->        The delay in milliseconds
        click        ->        true if user has to click to reveal | false for auto reveal
