- logic is just straight path 
- needs a lot of love

Junk to be cleaned

Feat: first iteration of equivalent tree checker implementation

Refactor: deprecate `whoDefinesMethod:` with `whichClassIncludesSelector:`

Refactor: improve naming and add comments to EquivalentTreeChecker

Test: data for testing EquivalentTreeChecker

Feat: using new EquivalentTreeChecker in ExtractMethodTransformation!!!

Cleanup: deprecation rewrites of `whoDefinesMethod:` -> `whichClassIncludesSelector:`

Cleanup: deprecation rewrites of `mehtod` -> `compiledMethod`

Test: add comments for equivalent tree checker

Refactor: rename `checkEquivalentTreeFor:` -> `findEquivalentTreeFor:`

Rename: `RBExtractMethodTransformation` -> `ReCompositeExtractMethodRefactoring`

Cleanup: remove bunch of dead code in `ReCompositeExtractMethodRefactoring`

Refactor: change api of RemoveSubtreeTransformation

Refactor: remove popup from extract setUp method refactoring
