=== DOM creation ===

/**
 * Create a new DOM node for the current document.
 *    Basic usage:  var mySpan = newNode('span', "Hello World!")
 *    Supports attributes and event handlers*: var mySpan = newNode('span', {style:"color: red", focus: function(){alert(this)}, id:"hello"}, "World, Hello!")
 *    Also allows nesting to create trees: var myPar = newNode('p', newNode('b',{style:"color: blue"},"Hello"), mySpan)
 *
 * *event handlers, there are some issues with IE6 not registering event handlers on some nodes that are not yet attached to the DOM,
 * it may be safer to add event handlers later manually.
