  17  *  Modified for dojo loader, and to fit into dojo namespace. This was done by passing
  18  *  dojo object to anonymous function, then assigning Sizzle to dojo.Sizzle instead of window.Sizzle.
  19  *  Then an alias for dojo.query and dojo._filterQueryResult(). dojo.psuedos is not mapped.
  20  *  Finally, dojo.provide/require added.
