Description

I am occasionally seeing a need to do exponential averaging of values or rates.

Hbase guys want this as well.

So it is time to do it. I have a patch that does the averaging of values according to
http://tdunning.blogspot.com/2011/03/exponential-weighted-averages-with.html

I will attach that as a patch now and do the rate averaging as well before committing.
