heck 0.4.1

heck is a case conversion library.
# 0.4.1


- Add Train-Case support

# 0.4.0

Breaking changes:

* Make unicode support optional (off by default). Enable the `unicode` crate
  feature if you need unicode support.
* Rename all traits from `SomeCase` to `ToSomeCase`, matching `std`s convention
  of beginning trait names with a verb (`ToOwned`, `AsRef`, …)
* Rename `ToMixedCase` to `ToLowerCamelCase`
* Rename `ToCamelCase` to `ToUpperCamelCase`
* Add `ToPascalCase` as an alias to `ToUpperCamelCase`
