/*************************************************************************************\
 * Name:	BrowserAPI()
 * Author:	Greg Miley
 * Date:	03April02
 * Description:	
 *		Provide clean access to browser objects.
 *		Right now you must provide a StringID for the element you wish
 *		to access. This API wrapper provides access to DOM as well as
 *		older version 4's of IE and NN. Read the internal documentation
 *		comments for further explanation of each method/property.
 * Usage:
 *		1) Create a new instance of the object.
 *			var Browser = new BrowserAPI();
 *		2) Access objects via Browser.ObjRef('ObjIDString')
 *			Browser.ObjRef('mySpan').id = "mySpan";
 *			2.1) Move Items to specified postions.
 *				Browser.ObjRef('mySpan').MoveTo(nX,nY);
 *			2.2) Show and Hide items in document.
 *				Browser.ObjRef('mySpan').Show();
 *				Browser.ObjRef('mySpan').Hide();
 *			2.3) Resize Items to specified size.
 *				Browser.ObjRef('mySpan').Resize(nX,nY);
 *		3) Access styles via Browser.StyleRef('ObjIDString')
 *			Browser.StyleRef('mySpan').border = "1px #000000 solid";
 * Notes:
 *		More to come on this development. I will be adding more 
 *		methods as I complete them. Comments or suggestions to 
 *		greg_s_miley@hotmail.com
 *
 *		As a rule you MUST have styles set for alot of stuff
 *		to be accessed correctly. This is true whether you use
 *		this API or not. This API does NOT set up initial style
 *		for you. You have to do that yourself.
 *
 * Modification History:
 *	Name		When		Why
 **========================================================
 *	g miley		04.05.02	Added .Show() .Hide() and .MoveTo(X,Y)
 *	g miley		04.05.02	Added .Resize()
