Hello Dan.

Really sorry for the (long!) delay in examining your contribution.
I've noticed that the patch does not provide unit tests; could you please add some?

> I'd like to propose an enhancement to org.apache.commons.math.stat.Frequency.  I need
to "merge" multiple Frequency objects, and it would be great if Frequency had inherent support
for this, such as:
> public void merge(Frequency other);
> public void merge(Collection<Frequency> others);
> I'd be happy to submit a patch if that would help...
