// GaussianTail provides random variates from the upper tail of a Gaussian
// distribution with standard deviation sigma. The values returned are
// larger than the lower limit a, which must be positive. The method is
// based on Marsaglia's famous rectangle-wedge-tail algorithm (Ann. Math.
// Stat. 32, 894­899 (1961)), with this aspect explained in Knuth, v2,
// 3rd ed, p139,586 (exercise 11).
