<P>
Deterministic seed generator for pseudo-random number generators.
 The sole purpose of this class is to decorrelate seeds and uniform random number generators.
 (If a generator would be used to generate seeds for itself, the result could be correlations.)
 <p>
 This class has entirelly deterministic behaviour:
 Constructing two instances with the same parameters at any two distinct points in time will produce identical seed sequences.
 However, it does not (at all) generate uniformly distributed numbers. Do not use it as a uniformly distributed random number generator! 
 <p>
 Each generated sequence of seeds has a period of 10<sup>9</sup> numbers.
 Internally uses <A HREF="../../../../cern/jet/random/engine/RandomSeedTable.html" title="class in cern.jet.random.engine"><CODE>RandomSeedTable</CODE></A>.
