Initial commit.  enigma.py does not work yet.
Messages encrypted with a setting will decrypt with same setting
provided they are initialized to settings AAA (i.e. stepping doesen't
yet work).
Cleaned up comments; Messages can be encrypted and decrypted for a given
cipher, but this implementation still does not match the reference
implementation given by professor
