  * There are three levels of tradeoff of speed vs memory Because java has no
  * preprocessor, they are written as three separate classes from which to choose
- * 
+ *
  * The fastest uses 8Kbytes of static tables to precompute round calculations, 4
  * 256 word tables for encryption and 4 for decryption.
- * 
+ *
  * The middle performance version uses only one 256 word table for each, for a
  * total of 2Kbytes, adding 12 rotate operations per round to compute the values
  * contained in the other tables from the contents of the first
- *
