Extracts a fisher_f_distribution random number distribution __x from the input stream __is.

class std::fisher_f_distribution< _RealType >"A fisher_f_distribution random number distribution.

The formula for the normal probability mass function is     [
   p(x|m,n) = ac{Gamma((m+n)/2)}{Gamma(m/2)Gamma(n/2)}
              (ac{m}{n})^{m/2} x^{(m/2)-1}
              (1 + ac{mx}{n})^{-(m+n)/2}  ]
