DoubleTake for PC and Mac

1. DoubleTake is an XCode extension that removes duplicate imports, @class and @protocol.

2. The inspiration behind this extension is that I was working on a legacy project which contained many duplicate imports.

3. This became a pain to do by hand so like any good developer I automated it.

4. It works in both Objective-C and Swift projects.

5. Hopefully, this will help you too and remove some headaches in your projects.
