+// Ran088: L'Ecuyer's 1996 three-component Tausworthe generator "taus88"
+//----------------------------------------------------------------------------//
+// 
+// Returns an integer random number uniformly distributed within [0,4294967295]
+//
+// The period length is approximately 2^88 (which is 3*10^26). 
+// This generator is very fast and passes all standard statistical tests.
+//
+// Reference:
+//   (1) P. L'Ecuyer, Maximally equidistributed combined Tausworthe generators,
+//       Mathematics of Computation, 65, 203-213 (1996), see Figure 4.
+//   (2) recommended in:
+//       P. L'Ecuyer, Random number generation, chapter 4 of the
+//       Handbook on Simulation, Ed. Jerry Banks, Wiley, 1997.
+//
+//----------------------------------------------------------------------------//
+
+//----------------------------------------------------------------------------//
+// I chose this random number generator for the following reasons:
+//		fast. 
+//		easier and faster to seed than other high quality rng's such as Mersenne Twister.
+//		the internal state is only 12 bytes.
+//		the period is long enough for music/audio.
+//		possible to code in altivec in future if needed.
