     *   <code>Event</code> interface specified is supported by the

     *   implementation this method will return a new <code>Event</code> of

     *   the interface type requested. If the <code>Event</code> is to be

     *   dispatched via the <code>dispatchEvent</code> method the

     *   appropriate event init method must be called after creation in

     *   order to initialize the <code>Event</code>'s values. As an example,

     *   a user wishing to synthesize some kind of <code>UIEvent</code>

     *   would call <code>createEvent</code> with the parameter "UIEvents".

     *   The <code>initUIEvent</code> method could then be called on the

     *   newly created <code>UIEvent</code> to set the specific type of

     *   UIEvent to be dispatched and set its context information.The

     *   <code>createEvent</code> method is used in creating

     *   <code>Event</code>s when it is either inconvenient or unnecessary

     *   for the user to create an <code>Event</code> themselves. In cases

     *   where the implementation provided <code>Event</code> is

     *   insufficient, users may supply their own <code>Event</code>

     *   implementations for use with the <code>dispatchEvent</code> method.

     * @return The newly created <code>Event</code>
