-//! **heck** is a case conversion library.
-//!
-//! This library exists to provide case conversion between common cases like
-//! CamelCase and snake_case. It is intended to be unicode aware, internally
-//! consistent, and reasonably well performing.
-//!
-//! ## Definition of a word boundary
-//!
-//! Word boundaries are defined as the "unicode words" defined in the
-//! `unicode_segmentation` library, as well as within those words in this
-//! manner:
-//!
-//! 1. All underscore characters are considered word boundaries.
-//! 2. If an uppercase character is followed by lowercase letters, a word
-//! boundary is considered to be just prior to that uppercase character.
-//! 3. If multiple uppercase characters are consecutive, they are considered to
-//! be within a single word, except that the last will be part of the next word
-//! if it is followed by lowercase characters (see rule 2).
-//!
-//! That is, "HelloWorld" is segmented `Hello|World` whereas "XMLHttpRequest" is
-//! segmented `XML|Http|Request`.
-//!
-//! Characters not within words (such as spaces, punctuations, and underscores)
-//! are not included in the output string except as they are a part of the case
-//! being converted to. Multiple adjacent word boundaries (such as a series of
-//! underscores) are folded into one. ("hello__world" in snake case is therefore
-//! "hello_world", not the exact same string). Leading or trailing word boundary
-//! indicators are dropped, except insofar as CamelCase capitalizes the first
-//! word.
-//!
-//! ### Cases contained in this library:
-//!
-//! 1. UpperCamelCase
-//! 2. lowerCamelCase
-//! 3. snake_case
-//! 4. kebab-case
-//! 5. SHOUTY_SNAKE_CASE
-//! 6. Title Case
-//! 7. SHOUTY-KEBAB-CASE
-//! 8. Train-Case
