Implements hashing for `HashSet` or `HashMap` themselves. Enables a map of maps to values, or a map of sets to values.

## Library Usage

Wherever a hashable `HashSet` or `HashMap` is needed, wrap it in a `SumHashes`.

If you have unordered collections from third-party crates, wrap them in `SumHashesAnyCollection`, which uses the default hasher per-element.

### Safety

* The library contains no unsafe code
* The library should never panic

## Dependency

Add this library to your Cargo.toml:

```toml
[dependencies]
hash-that-set = "0.1"
```

## Notes

If you ever happen to notice a place where a standard trait could be implemented, please open an issue or PR in this repository.
