stats_cdf_laplace — Calculates any one parameter of the Laplace distribution given values for the others
Returns the cumulative distribution function, its inverse, or one of its parameters,
of the Laplace distribution. The kind of the return value and parameters
(par1, par2, and par3)
are determined by which.
The following table lists the return value and parameters by which.
CDF, x, mu, and b denotes cumulative distribution function, the value of the random
variable, and the location and the scale parameter of the Laplace distribution, respectively.

| 2 | x | CDF | mu | b |
| 3 | mu | x | CDF | b |
| 4 | b | x | CDF | mu |
par1The first parameter
par2The second parameter

whichThe flag to determine what to be calculated
Returns CDF, x, mu, or b, determined by which.
