Creates a DEmpirical based on a probability mass function

Assigns the probability associated with each cdf value to the integers starting at 0.

Makes a pair array that can be used for the parameters of the DEmpiricalCDF distribution

Assigns the probability associated with each cdf value with the integers starting at the start value.

This method takes in an Array of probability points (value, cumulative probability), e.g., X[] = {v1, cp1, v2, cp2, ...}, as the input parameter and makes a 2D array of the value/prob pairs
