---------------------------------------------------------
update to syntax:
*Exponential Moving Average Evaluator:*
expMovingAvg(colA, windowSize) - calculates smoothing factor (alpha) as
2/windowSize + 1
OR
expMovingAvg(colA, windowSize, smoothingFactor) - user defined alpha
*Binomial Coefficient Evaluator:* - wraps Apache Commons Math implementation,
number of ways to pick k unordered outcomes from list n
binomialCoefficient(n, k)
