24      Parses the pymongo.json_util encoding of a datetime instance. The instance is 
25      encoded as a 64-bit unsigned integer for milliseconds since epoch, according to 
26      JSON strict mode. This method also assumes the strict mode packaging of a dict 
27      using $date as the key for this integer.

30      { "$date" : 1283505509571} 
31   
32      @param date_string: JSON encoded datetime instance 
33      @type  date_string: dict with the date integer stored at $date

35      @return: python object representing the date
