scala Cipher -encrypt key filename --- Applies the key to the text in filename.

scala Cipher -decrypt key filename1 > filename2 --- Decrypts the text in filename1 and puts it in filename2.

scala Cipher -crib suppKey filename --- Tries breaking the code by assuming suppKey appears somewhere in filename.
