//! Credit Card is a library for adding credit cards
//! to any project.
//!
//! ```rust,no_run
//! use credit_card::CreditCard;
//!
//! let mut cc = CreditCard {
//!     number: "4111111111111111".to_string(),
//!     cardholder_name: "Graydon Hoare".to_string(),
//!     expiration_month: "01".to_string(),
//!     expiration_year: "2023".to_string(),
//!     brand: None,
//!     security_code: None
//! };
//! cc.apply_brand();
//! ```
//!
//! # Current Features
//! - Create CreditCards
//! - Add brand to credit cards from card number
//! - Validate credit card number
//!
//! # Future Features
//! - Validate CVV
//! - Validate Address
//! - ...
//! - Full card validation
//!
//! ### Notice:
//! This is under development right now, so interfaces
//! and apis will be changing.  If you are interested
//! in using this please create an issue or reach out
//! with your feature request so I can help add it.
//!
