[Refactor] Rename/update MovingAverage to MathematicalSeries

We want the MovingAverage functionality to be more generic and useful
than just doing a moving average calculation. The new functionality
allows for the calculation of the standard deviation and supports a
generic type (so it can be used with integers and floats).
