//! The color counter crate is a CLI tool
//! to open an image and count it's pixel colors
//! and divide this count by color region.
//!
//! The Space is the color space in its entirety,
//! the Region is a piece of the color space.
//!
//! There is also a constants module, to define the boundaries
//! of the color space, this is used to divide the color space
//! and put every color on its 'bucket'.
