* This version from github, dated 1/23/2009, commit: e374a73bbffc12ec3b5f252e7f76e593c508dfa5
* Modified for dojo loader, and to fit into dojo namespace. This was done by passing
* dojo object to anonymous function, then assigning Sizzle to dojo.Sizzle instead of window.Sizzle.
* Then an alias for dojo.query and dojo._filterQueryResult(). dojo.psuedos is not mapped.
* Finally, dojo.provide/require added.
