//! A simple example of using the playfair_cipher_rs crate.
//! This example uses the Playfair Cipher to encrypt a message.
//! The key is "playfair example" and the plaintext is "Hide the gold in the tree stump".
//! The ciphertext should be "BMODZBXDNABEKUDMUIXMMOUVIF".
//! The ciphertext is printed to the console.
//! This example is based on the example in the Wikipedia article on the Playfair Cipher.
