input: Write a python function to initialize an Enigma machine with given rotors, reflector, ringsetting, and plugboard, and test its encryption and decryption methods.
  assert enigma.encrypt("HELLO") == "ILBDA"
  assert enigma.decrypt("ILBDA") == "HELLO"
  assert enigma.encrypt("WORLD") == "XPQEM"
  assert enigma.decrypt("XPQEM") == "WORLD"
