/**
* A base class for indicator series with simple calculations that separates the calculation
* responsibility from the other responsibilities of the financial series, this enables
* easier unit testing and decoupling of individual calculation strategies.
* A contract is defined between the financial series and these simple indicator calculations
* detailing the data which the series agrees to provide the simple indicator calculations,
* this contract is defined by
* FinancialCalculationDataSource. If more
* complex interactions are needed between the indicator calculation and the series, the
* indicators should instead derive from
* FinancialIndicator directly, or some
* derivative other than
* StrategyBasedIndicator
