-In the examples folder there is a file named `statistics.cpp`.
-This example demonstrates how to parse a file, and then leverage Boost.Math to compute statistics of that data set culminating with the values of the Bollinger Bands.
-This example could be extended with the simple moving average to create full bands based on the period of the moving average you would like.
