Detailed Description

template<class T>
class Stats::RunCalc< T >

Calculates mean, min, max etc., as running values.

The idea is that you simply add values and ask for a stat whenever needed. The clear() method resets the object and makes it able to work with new data.

Adding values can be doing with weight (addValue) or without (operator +=). You can remove a value; for Min or Max this has no effect as this would require buffering all data.
