Explain proof-of-history in the readme
...
Also:
* Hash userdata so that verification works as the readme describes.
* Drop itertools package. Found a way to use std::iter instead.
Fixes #8

Update benchmark
...
* Add asm, though it doesn't make it faster. TODO: use avx instructions.
* Do 10x less hashes, since sha256 is more expensive.

Use sha256 hashes instead of Rust's builtin hasher.
...
Causes a 20x performance degradation. Enabling asm did not
speed things up.

Reset historian's hasher between events

Hasher will generate different hashes for the same input if it
had already generated a hash.
Also add a binary to ensure the example in the README works.

Make it so the parallel and sequential verification implementations
are only different in one line.
For reasons I don't understand Rayon's `all()` isn't `mut`.

Rename Tick to Event
...
* Define a tick to be an event with no user data.
* Use the term "event log" for now.
** Reserve the word "entry" for hash entries, and "item" for array items.
** Reserve the word "blockchain" for when the event is a block of something.
** Reserve the word "ledger" for when the event is of a particular type,
such as transactions.
