- Grey: 8
- White: 9
-The goal of this exercise is to create a way:
-- to look up the numerical value associated with a particular color band
-- to convert the numerical value into a string representing color
-- to list the different band colors

For task number one, you will need the external crate [`int-enum`](https://docs.rs/int-enum/0.5.0/int_enum/) and for task number three, you'll need [`enum-iterator`](https://docs.rs/enum-iterator/1.2.0/enum_iterator/).
They're both already included in this exercise's `Cargo.toml`.
