// OverlayMessage.js - HTML transparent overlaid message
//
// Using these routines is very easy.
//
// 1) In your HTML, make an element for the message to appear over.  Give
//    it whatever style attributes you like:
//
//        <div id="container" style="width: 100%; height: 7in;"></div>
//
// 2) Load the routines into your code:
//
//        <script src="http://www.acme.com/javascript/OverlayMessage.js" type="text/javascript"></script>
//
// 3) Create an OverlayMessage object, passing it the HTML element:
//
//        var om = new OverlayMessage( document.getElementById( 'container' ) );
//
// 4) Call the Set method when you want a message to appear:
//
//        om.Set( 'Loading...' );
//
// 5) Call the Clear method when you want the message to go away:
//
//        om.Clear();
//
// That's it!  Everything else happens automatically.
//
