Test recording and replaying

[JackYoustra]

Hello all!

Sometimes I get tired of writing my test cases or analyzing error logs, especially high level instances which interact with multiple components, and want some way of recording them and playing them back, much like with the record button on Xcode's UI tests.

I made a package which does just this! https://github.com/JackYoustra/TCATestRecording

Let me know what you think, how it can be extended, and if you have any ideas with how to automatically stub dependencies / create a time traveler as mentioned in an accompanying blog post.
