* First steps toward refactoring Statistical Distributions into smaller classes: BETA() and GAMMA() (and related functions) to start with... they all need a lot of tidying up, and more testing; but it's a start * Add basic datatype validations to Beta and Gamma Excel function implementations * Switch to using a trait with the validation methods to provide easier sharing between distribution classes * Additional unit tests for Beta and Gamma functions, including unhappy path for validations * Extract ChiSquared functions * Additional argument validation checks with unit tests for Chi Squared functions * Extract Fisher * Move MEDIAN() and MODE() to the Averages class * Extract filters for Median and Mode for common usage
