Rearrange is a collection of utilities for making it easier to work with NSRange, IndexSet, NSTextRange/UITextRange, and NSTextLocation.

]RangeMutation
This is a struct that encapsulates a single change to an NSRange. It's useful for serializing, queuing, or otherwise storing changes and applying them.
You can also use this class to tranform locations, NSRange, or even an IndexSet. This is handy for updating values as text is changed. This might seem easy, but there are a large number of edge cases that RangeMutation handles, including mutations that invalidate (for example completely delete) a range.

I prefer collaboration, and would love to find ways to work together if you have a similar project.
I prefer indentation with tabs for improved accessibility. But, I'd rather you use the system you want and make a PR than hesitate because of whitespace.
