//! There it is! The first DKIM Rust library!  
//!   
//! # Goals  
//!  
//! When one of the three steps is completed, the minor version is incremented.
//! As long as the major version is 0, any update can introduce breaking changes.
//!
//! 1. Make it work
//!     - [x] Relaxed canonicalization algorithm
//!     - [x] Simple canonicalization algorithm
//!     - [x] Verifying
//!     - [x] Signing
//!     - [x] Documentation
//!     - [x] Sha256
//!     - [x] Sha1
//! 2. Make it stable and robust
//!     - [ ] Fulfill each "MUST" of the RFC
//!     - [ ] Fulfill each "SHOULD" of the RFC
//!     - [ ] Write tests
//!     - [ ] Eradicate unwraps
//! 3. Make it fast
//!     - [ ] Benchmarks
//!     - [ ] Compare to other implementations
//!     - [ ] Optimize

/// canonicalization functions
