/*
To Add a button and associated dropdown menu:
(1) Place a button in the page
	Ex: <img  name="ebooks_img" id="ebooks_img"></td>

(2) Include this file in the page
	Ex:	<script language="JavaScript" src="http://www.lsro.org/ddm.js" type="text/javascript"></script>

(3)	define the button object in the [initialize()] function
	Ex: obj_ebooks_button=document.getElementById? document.getElementById("ebooks_img") : ebooks_img

(4) Register the button object so that mouse events are captured
		- also done in the [initialize()] function
	Ex:	register_object (obj_ebooks_button)

(5) Enter the image id in the buttonList[] array
	Ex:	buttonList[6] = "ebooks_img"
	
(6) Enter the image local name id in the buttonImgList[] array
		Note: this is the name that will have '_hi' or '_lo' 
			appended to it to create an image object for controlling hilighting
	buttonImgList[6] = "btn_ebooks"

(7) Create an array that defines the topmenu for the button;
		the array entry is a list containing:
		- an id for the topmenu item
		- the link for the topmenu item
		- the topmenu item label
	Ex:		var menu6=new Array()
			menu6[0]='<a id="mediaPressReleases" href="http://www.lsro.org/media_press_releases.html">Press Releases</a>'
			menu6[1]='<a id="mediaContact" href="http://www.lsro.org/media_contact.html">Media Contact</a>'

(8) Enter a topmenu definition for the button in the allMenus[] array
		consisting of a list:
		- button id
		- keyword 'topMenuName'
		- name of array defining the topmenu
		- menuwidth in pixels
	Ex: allMenus[52] = "ebooks_img,topMenuName,menu6,110"		// topmenu definintion
