Performance equation to calculate tag median over time range

Currently we do not have functionality to calculate a median over a set of tag archive values. For example a function such as TagMed('sinusoid', '*-2h', '*-30m') to return the median of that set of archive values.

    Calculation of median among a set of values probably should be event based and not time based. While TagAvg historical has been time based, it has been enhanced to be optionally event based. There exist a Median() function to calculate event based median. If I have misunderstood this idea, please provide further clarification.

    TagMedian would be very interesting. It could be like TagMean but getting de median value between these timestamps based on events (by making this option available in analysis, summaries, RTQP, Event Frames templates...).

    The user might also want a tag median based on the last nos. of events, not just timebound.
