The Weekdays crate provides a simple Weekdays
type for representing days of the week bit-mapped in a single byte, and
functionality for working with them.
This is particularly useful when representing a set of days in a database field or similar.
Each bit represents a day of the week. The bits are ordered from most significant to least significant, starting from Monday, with the least significant bit representing Sunday.
