The specification for RC5 came from the RC5 Encryption Algorithm
publication in RSA CryptoBytes, Spring of 1995.
http://www.rsasecurity.com/rsalabs/cryptobytes.
This implementation has a word size of 32 bits.
Implementation courtesy of Tito Pena.

forEncryption | whether or not we are for encryption. |

params | the parameters required to set up the cipher. |
IllegalArgumentException | if the params argument is inappropriate. |

Process one block of input from the array in and write it to the out array.
in | the array containing the input data. |

inOff | offset into the in array the data starts at. |
out | the array the output data will be copied into. |
outOff | the offset into the out array the output will start at. |
Reset the cipher. After resetting the cipher is in the same state as it was after the last init (if there was one).
