virtual  ~SSTRandom () 
Destroys the random number generator.  
Implements a Mersennebased RNG for use in the SST core or components.
The Mersenne RNG provides a better "randomness" to the distribution of outputs but is computationally more expensive than the Marsaglia RNG.
MersenneRNG::MersenneRNG  (  unsigned int  seed  ) 
Create a new Mersenne RNG with a specified seed.
[in]  seed  The seed for this RNG 
References seed().
MersenneRNG::MersenneRNG  (  ) 
Creates a new Mersenne using a random seed which is obtained from the system clock.
Note this will give different results on different platforms and between runs.
