// The message object is used to display a "popup" window using division instead of a new window.
//
// The message creates the following HTML objects:
//		msgBox - outside wrapper for popup message
//		msgTitle - title for popup message
//		msgContent - content/message for popup message
//		msgSrc - iframe used for loading content from file.  The file loaded must contain a "msgContent" division.
//
//	The message object requires the following CSS objects:
//  	.message - defines how the message box should look
//		#msgTitle - defines how the title should be formatted
//    #msgContent - defines how the content should be formatted.
//    .msgButton - defines how the close button should be formatted
// 
// The message popup is called using the showMessage() function.
//		showMessage (title,content,x,y)	
//		showMessage (title,content,object)
//		showMessage (title,division,x,y)
//		showMessage	(title,division,object)
//		showMessage (title,document,x,y)
//		showMessage	(title,document,object)
//		showMessage	(title,document,object,relX,relY)
//where
//    title is a html formatted title to display for the popup.
//		content is a html formatted content to display for the popup.
//		x is the x screen coordinate where the left end of the popup should be.
//		y is the y screen coordinate where to center the content.
//		object is the name of an object to use for determining the x,y coordinates.
//		division is the name of a division on the page containing the content for the popup.
//		document is the name of a document containing the content for the popup.  The document must contain a msgContent division.
//		relX is the number of pixels left or right relative to the object to place the popup.
//		relY is the number of pixels up or down relative to the object to place the popup.
//
//finally
//The message object can be accessed directly using the following methods.
//		alignToObject(object,x,y)
//		setMessage(html formatted text);
//		setMessageFromDiv(name of division or file);
//		setTitle(html formatted text);
//		setXY(x,y);
//		show();
//		hide();
