Remarks
C#
Return F-distributed (variance ratio distributed) random deviates
with n numerator degrees of freedom and d denominator degrees of freedom
according to the density:

  p   (x) dx =  ... dx
   n,d

Both paramters n and d must be positive.

Method: The random numbers are directly generated from ratios of
        ChiSquare variates according to:

 F = (ChiSquare(n)/n) / (ChiSquare(d)/d)
