A small wrapper library to simplify common RBRefactoring operations when generating code.
The main pupose is to prepare all code that you want to generate before hand and represent them as RBRefactorings, so you can review them before you accidentally break your system. ;)
On top of the generation, this library also fixes couple RBRefactoring issues, where RBRefactoring would show (and try to execute) a change that doesn't actually change anything. We filter this out, so you see only actual changes.
