Tested yielded good results with the generics (using TFPGMaps gave me the
sort code I need for testing), but the IDE itself didn't like the generics
(jump to implementation, and procedure list both failed in random ways
including the entire IDE vanishing twice), so I'm thinking generics
shouldn't be added to the LCL until the IDE fully supports them.   On the
TIntegerList front, I refactored the code several times over, and the
current implementation doesn't use an integerlist at all.  Many thanks for
the feedback, and the link to your code...
