//! \brief Methods for generating random numbers.
/*!
  
    The MRandom class implements several methods to generate sequences of 
	random numbers.

	For a given fixed seed, input i produces the i'th random number of a
	2^64-long pseudo-random sequence.  Different seeds will give different 
	sequences, but nearby seeds may on rare occasion exhibit statistical 
	correlations; it is therefore best to use hashed seeds.

	All methods are thread-safe, values can be requested in any order, and
	sequences are repeatable.
