*Time Series Differencing Evaluator:*

difference(colA) - calculates differencing with the default of lag one. 
OR
difference(colA, lag) - calculates differencing with a user defined lag

Tests included for nested double differencing to remove trends and seasonality, 
e.g. difference(difference(colA), lag)

Mann-WhitneyU test wraps Apache Math Commons implementation.

*Mann-Whitney U Test:*  
mannWhitneyU(colA, colB) - Performs Mann-WhitneyU Test on 2 arrays of numbers 
and returns a a single tuple of *u-statistic* and *p-value*.

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)
