Description
I tried to calculate the median of an empty range
median(x.begin(), x.end(), true)
where x is empty so x.begin()==x.end(). The program crashes with segmentation fault. I think yat should detect this and either return NaN or throw an exception.
Opinions?

Given that Averager::mean() returns NaN when empty, I think median should also return NaN.
