-
-// The Mersenne Twister is an algorithm for generating random numbers. It
-// was designed with consideration of the flaws in various other generators.
-// The period, 2^19937-1, and the order of equidistribution, 623 dimensions,
-// are far greater. The generator is also fast; it avoids multiplication and
-// division, and it benefits from caches and pipelines. For more information
-// see the inventors' web page at
-// http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html

-// Change log:
-//
-// v0.1 - First release on 15 May 2000
-// - Based on code by Makoto Matsumoto, Takuji Nishimura, and Shawn Cokus
-// - Translated from C to C++
-// - Made completely ANSI compliant
-// - Designed convenient interface for initialization, seeding, and
-// obtaining numbers in default or user-defined ranges
-// - Added automatic seeding from /dev/urandom or time() and clock()
-// - Provided functions for saving and loading generator state
-//
-// v0.2 - Fixed bug which reloaded generator one step too late
-//
-// v0.3 - Switched to clearer, faster reload() code from Matthew Bellew
-//
-// v0.4 - Removed trailing newline in saved generator format to be consistent
-// with output format of built-in types
-//
-// v0.5 - Improved portability by replacing static const int's with enum's and
-// clarifying return values in seed(); suggested by Eric Heimburg
-// - Removed MAXINT constant; use 0xffffffffUL instead
-//
-// v0.6 - Eliminated seed overflow when uint32 is larger than 32 bits
-// - Changed integer [0,n] generator to give better uniformity
-//
-// v0.7 - Fixed operator precedence ambiguity in reload()
-// - Added access for real numbers in (0,1) and (0,n)
-//
-// v0.8 - Included time.h header to properly support time_t and clock_t
-//
-// v1.0 - Revised seeding to match 26 Jan 2002 update of Nishimura and Matsumoto
-// - Allowed for seeding with arrays of any length
-// - Added access for real numbers in [0,1) with 53-bit resolution
-// - Added access for real numbers from normal (Gaussian) distributions
-// - Increased overall speed by optimizing twist()
-// - Doubled speed of integer [0,n] generation
-// - Fixed out-of-range number generation on 64-bit machines
-// - Improved portability by substituting literal constants for long enum's
-// - Changed license from GNU LGPL to BSD
-//
-// v1.1 - Corrected parameter label in randNorm from "variance" to "stddev"
-// - Changed randNorm algorithm from basic to polar form for efficiency
-// - Updated includes from deprecated <xxxx.h> to standard <cxxxx> forms
-// - Cleaned declarations and definitions to please Intel compiler
-// - Revised twist() operator to work on ones'-complement machines
-// - Fixed reload() function to work when N and M are unsigned
-// - Added copy constructor and copy operator from Salvador Espana
