[Glass] Finding instances of old (removed) classes

[Dale Henrichs via Glass]

Paul,

I'd like to know a little bit more about what you are trying to 
accomplish ...

If I assume that the references to the orphaned classes are instances of 
the orphaned class  then you will want to migrate those instances to the 
new version of the class.

If those references are not from instances of the orphaned class - a 
direct reference to the orphaned class (as a key in a dictionary or 
something similar) then migration will not solve your problem ... you 
will have to do a findAllReferencePathsToObject .... and find clean up 
the references.

For instance migration you should do some similar to 
GsDeployer>>doBulkMigrate: where the `classList` is your list of 
orphaned classes ..
