Description

Hi there,
is there a specific reason FirstMoment is not public?
I want to calculate a mean over a List<Double>, for that I want to loop over that list and invoke Mean.increment(listValue), however this is slower than it could be. Every increment call makes a check to incMoment.
I could avoid that if I use a FirstMoment directly, but I cannot create an instance, because it is protected.

Also this effectively means that the public constructor Mean(FirstMoment) is not usable.
