Fully configurable as per the spec. Includes a new type, in addition to
i, d, and id: u. Similar to id in that it is a hybrid solution, but
slightly tweaked to be unique to Urbit's implementation.
Initially implemented as a direct port from the pure Python
implementation, then lightly rewritten to be more Hoon-ish.

It now contains features it was missing, and those have been verified
for correctness. Behaves more like an object now, with initialization
and state change arms, and easy ways to get data out.
Library file includes wrappers for the SHA family to make it take and produce sane byte order data, and a new HMAC implementation that depends on it.
Also includes @belisarius222's secp256k1 implementation, plus experimental (and broken) support for other secp variants.
