Subject: Figured out that our previous act of just assigning TypeReference
 objects directly to other nodes (e.g. from a FieldDeclaration's type to a
 method argument) is NOT a good idea, as this screws up when the TypeReference
 object represents a generic type (like 'T') - each instance of a generic type
 has a different resolution, but 1 TypeReference object can only hold 1
 resolution.

Thus, a copyType() method has been written, and the Handle* classes have been updated to use it.

Also, generateEquals() is half-finished in HandleData.
