Detailed Description

Base class of random number generators.

This class defines the interface of random number generator, and implements common methds. Practical methods to generate random numbers are defined in subclasses. This class also implements Gaussian random number and method to set a global field of Gaussian random numbers and cut it out to the local field for the own node (gauss_lex_global()) which is useful in HMC etc. [25 Dec 2011 H.Matsufuru]
