/** How to handle a strict rename. I.e. a field/method is renamed,
 * but type, signature and semantics have not changed.
 * In addition all invocations have been appropriately renamed. 
 * Best solution would probably be to either: 
 * 1) preprocess the new classfiles to undo/hide the rename, OR 
 * 2) preprocess the old classfiles/coverage info to reflect the new name.   
 * 
 * In addition, we need to somehow detect a renaming.
