Description:                      PyMT64
                             
        PyMT64 is a Python version of the Mersenne Twister (MT) 64-bit pseudorandom number generator by Takuji Nishimura and Makoto Matsumoto (see http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt64.html and the references below).
        
        This customised version is thread safe and was interfaced from C to Python (see pymt64.c)
        
        This module provides the following methods:
        - init : initialisation of the state vector (mt) used by the pseudorandom number generator (PNG)
        - uniform : generation of an uniform distribution
        - normal : generation of two Normal distributions
        - poisson : generation of a Poisson distribution
        
        The period of the PNG is 2**19937-1.
        
        Example:
        	import time
        	import pymt64
        	seed = int(time.time()) # the initial seed
        	mt = pymt64.init(seed) # initialisation of the state vector of MT
        	u = pymt64.uniform(mt,10) # generation of an uniform distribution
        	print u
        	[ 0.94295421  0.47222327  0.634552    0.26012686  0.38431784  0.23995444
        	  0.02175826  0.8209848   0.79266556  0.8638286 ]
        
        For a complete example, see pymt64_test.py
        
        Note: the state vector 'mt' returned by pymt64.init has 313 elements instead of the 312 elements of the original C code. This is because the 313th element store the associated counter (mti).
