IObtainRating interface
This interface is used to obtain the rating (PICS label) for a URL.
It is entirely up to the server to determine how to come up with the
label.  The ObtainRating call may be synchronous.
GetSortOrder returns a ULONG which is used to sort this rating helper
into the list of installed helpers.  The helpers are sorted in ascending
order, so a lower numbered helper will be called before a higher numbered
one.
