While the term "refactoring" has fallen into common usage meaning
"change the code" the original intent, and the definition still used
in XP is:

 1. Refactoring. Noun. A very tiny modification to a program that
changes it's structure but does not change it's behavior as described
by existing unit tests.

2. Refactor. Verb. The act of making one or more refactorings to a
program for the purpose of improving it's structure.
