## before publish

- impl heapselect
	1. ensure `reverse` method is working
	2. publish
	3. look into non-`reverse` methods
- improve `break_patterns` randomization
	1. bench 1 more time
	2. consider implementation

## publish checklist

1. check for proper functionality
	- run tests
	- look through documentation for discrepancies
2. ensure `#[no_std]`

## other todos

- publish repo on github
- look into why the `Xoroshiro128` from the `xorshift` crate is slower
- consider including `tests` and `benches` directories
	- remove benches for other crates
	- remove other break versions

## unrelated

- look into how many iterations it takes for `stretch` stuff
