    …mpute Normal, ChiSquare and
    
    Poisson probabilities, Erf and Gamma functions.
    
    JIRA: MATH-282
    JIRA: MATH-301
    
    Summary of changes:
    
    * BrentSolver has been changed to expose its configured absolute accuracy. This solver is used by
      the default inverse cum implementation in AbstractContinuousDistribution and the hard-coded setting
      (1E-6) was limiting accuracy in inverse cumulative probability estimates. AbstractContinuousDistribution
      was changed to allow distributions to set this value and NormalDistributionImpl was changed to set it to
      1E-9 by default and allow users to configure it via a constructor argument.
    
    * AbstractContinuousDistribution and AbstractIntegerDistribution inverseCumulativeProbability methods
      have been modified to check for NaN values returned by cumulativeProbability and throw MathExceptions
      when this happens.
    
    * The criteria for choosing between the Lanczos series and continued fraction expansion when computing
      regularized gamma functions has been changed to (x >= a + 1). When using the series approximation
      (regularizedGammaP), divergence to infinity is checked and when this happens, 1 is returned.
    
    * When scaling continued fractions to (try to) avoid divergence to infinity, the larger of a and b is
      used as a scale factor and the attempt to scale is repeated up to 5 times, using successive powers
      of the scale factor.
    
    * The maximum number of iterations used in estimating cumulative probabilities for PoissonDistributionImpl
      has been decreased from Integer.MAX_VALUE to 10000000 and made configurable.
