Create Element and Event wrappers

Elements will not be manually extended in Fuse.
We should create an element wrapper to handle element manipulations.

// pseudo code

Fuse.addNS('Dom');

Fuse.Dom.Node = Fuse.Class(Fuse.Dom, {
  'constructor': (function() {
    function Node(element) {
      if (typeof element === 'string')
        element = Fuse._doc.getElementById(element || expando);
      if (typeof element.getUniqueID === 'function')
        return cache[element.getUniqueID()];
      this.raw = element;
    }
    return Node;
   })(),
});

Fuse.Dom.Node.Plugin.hide = function hide() {
  var element = this.raw,
   display = element.style.display;
  if (display && display !== 'none')
    element._originalDisplay = display;
  element.style.display = 'none';
  return element;
};
