A simple terminal progress bar in rust with a nice, type-driven, functional API.
Early stages of development so it's basic and rough around the edges.
The API is subject to substantial change.
Code based on Will Crichton's excellent talk, "Type-Driven API Design in Rust" (although any errors are my own), with some inspiration from tqdm.
A play on "cranc", which is Welsh for "crab" and "crank" as in "to crank the engine".
