lib.rs needs #![feature(no_std)]

[mtnygard]

Recent rust nightlies (at least as far back as 2015-11-19) require 'no_std' to be enabled as a feature before it can be used. Lacking that, the #![no_std] line results in a compile error:

The no_std feature was stabilized in rust-lang/rust#30187. It is already stabilized in the current beta version and will work on 1.6 stable. So it should work fine on current nightlies.

Whoops. You're totally right. Confirmed that it works on current nightly.
