* NLB Background Color Fader v1.0
* Author: Justin Barlow - www.netlobo.com
*
* Description:
* The Background Color Fader allows you to gradually fade the
* background of any HTML element.
*
* Usage:
* Call the Background Color Fader as follows:
*   NLBfadeBg( elementId, startBgColor, endBgColor, fadeTime );
*
* Description of Parameters
*   elementId - The id of the element you wish to fade the
*             background of.
*   startBgColor - The background color you wish to start the
*             fade from.
*   endBgColor - The background color you want to fade to.
*   fadeTime - The duration of the fade in milliseconds.
