/*
* This is the constructor function for DynEl objects.
* The arguments are the following:
* window: The Window object in which the dynamic element is to appear
* id: The HTML ID for the dynamic element. Must be unique.
* body: HTML text that constitutes the body of the dynamic element
* left: The optional initial X-coordinate of the element
* top: The optional initial Y-coordinate of the element
* width: The optional width of the element
*
* This constructor outputs a style sheet into the current document.
* This means that it can only be called from the of the document
* before any text has been output for display.

* Now we define a bunch of methods for the DynEl class.
* We define one set of methods if we are running in Navigator, and
* another set of methods if we are running in Internet Explorer.
* Note that the APIs of the methods are the same in both cases; it
* is only the method bodies that change. In this way, we define
* a portable API to the common DHTML functionality of the two browsers.
