Support for Standard Deviation Function in Dashboard

[vittalkini]

Can we have standard deviation function support in the dashboard ? One of the customer is looking to calculate standard deviation dynamically. Currently the way to achieve this is to calculate it in MV. This will not work as the standard deviation calculation will not change when the user filters the data or groups it based on different grouping dimension

Standard deviation is one of the standard function and would be good to have it supported as a runtime function in dashboard

In addition to this, a basic statistics package would be great! Percentile functionality would be fantastic.
