Usage :
*******************************************************************************
//This calls the javascript library
<script type="text/javascript" src="randomMessage.js"></script>
<script type="text/javascript">
// Creates a new object
var randMesg = new randomMessage();
// You must add at least two messages for this to work
randMesg.addMessage( "Testing 1");
randMesg.addMessage( "Testing 2");
randMesg.addMessage( "Testing 3");
// This will randomly select a message to be displayed
randMesg.init();
</script>
// You can use this to display the message in your HTML
<script type="text/javascript">randMesg.displayMessage</script>
//root you can call in another script with this
