This utility calculates summary values for a Pert distribution for specified values for minimum, mode and maximum values.

Inputs are the required minimum, mode, maximum values and a shape parameter for
the desired distribution and the required number of digits after the decimal point
in the output. The shape parameter determines the degree of concentration of the
distribution around the mode. The (commonly used) default value is 4. Larger values result
in greater concentration around the mode, while smaller values result in concentration
towards the tails.

Outputs are a table of percentiles, mean and mode and a density curve for the specified distribution.
