Estimate alpha and beta Parameters for Beta distributions from count data

This utility calculates the alpha and beta parameters for a Beta distribution, based on count data (x successes from n trials).

Required input are the sample size (n = number of trials) and the number of successes (x).

Outputs are the alpha and beta parameters, a numeric summary and a density curve for the distribution.
