Description

I find Hash256StdHasher kinda scary. How does it get used? It's assigned in https://github.com/paritytech/substrate/blob/master/primitives/core/src/hasher.rs#L47 but actually Hasher::StdHasher never gets used anywhere inside this repository. cc @jimpo

Document how Hash256StdHasher and StdHasher are intended to be used, including the apparent absence of in-repository uses; completion should leave the relationship and usage clear to readers.
