This is an edited version of a change set from Ted Kaehler that he says
that he has been using for around a year with no ill effects.

I updated it to correspond to our later changes.

However, I don't have time to fully test it (that is, to make
appropriate test cases for it).

I would appreciate it if someone could test this a bit; my inclination
is to approve it because it's coming from Ted.

I have been using it with no ill effects.

SmartReferenceStrm is in charge of converting reading in old .pr files
and taking care of instances of classes that have changed shape.  It
also handles obsolete classes.  It gives the user a chance to name a new
class that old instances will be converted to.  
	In 2000 Bob Arning made major changes, but these were never extended to
converting the instances of obsolete classes.  This changeSet fixes
that.
	
Ned Konz took Ted's code and merged in the later KCP and translation
changes.
