Remarks

This class efficiently lets you keep track of simple commutative statistics (such as total, average, sum of squares, and min/max) derived from the items of AList<T> and its variants (BList, BDictionary, and BMultiMap).

Note: this class relies on the "tree observer" feature of ALists, but SparseAList doesn't support tree observers as of 2020/01.

Typically a statistic tracker is created by calling an extension method on AList, BList, etc.
