ChangeLog
=========
0.3.0 (???)
-----------
* `stem` now takes `&mut self` instead of `&self`
* `stem_unsafe` renamed to `stem_str` since it is no more unsafe:
borrowchecker can verify that `stem` is not run again while there is
a reference to the returned `&str`
* added more tests
0.2.0 (2015-08-09)
------------------
* Completed the documentation
* Only compile `test.rs` when `cargo test` is runned
* Removed unnecessary use of `#[repr(packed)]
* Changed signature of `stem_unsafe`, which is now actually safe to
call but returns an unsafe to use pointer
0.1.1 (2015-06-23)
------------------
* Removed a silly `println`
0.1.0 (2015-06-23)
------------------
* Initial release
