 * RandomNumberGen is actually just a typedef for one of the many
 * RNGSequence classes available in IPPL.  It is selected by examining the
 * values of #define's.  Other RNGSequence classes may be used in a program,
 * but using RandomNumberGen give you the 'default' RNGSequence type as
 * selected at compile time.
 *
 * When using Random or Distributed number sequences, include this file.
