Rust Plain text OT library

This is a simple little rust library to compare writing OT code in rust vs javascript or C.

Surprisingly the rust implementation is the shortest of the three of them, clocking in at 319 loc vs JS's 357 loc or C's 800 loc.

The code is very new, and I'm still getting a handle on rust itself. Next step: Benchmarks.

I haven't put this code up on crates.io. Ping me if you want to use it for any reason and I'll put it up there.

Missing features:

No efficient rope library for efficient string inserts & deletes. Mind you, because of rust's type classes it should be possible to make this code work with very rich text types for editors.
No cursor position transformation code. Ranges and markers would be more efficiently handled by applying an operation to a range tree.
