Generate random numbers with a Weibull distribution

Synopsis
weibull(alpha, beta, shape)

Description
The weibull function will generate numbers that follow a Weibull distribution. I cannot find a mathematical definition of a probability density function that represents the output produced by this function.

Alpha parameter must be a non-zero number and beta can be any value. The result will be floating point numbers in the range 0 < x < $\infty$. The shape can be either an integer or a vector of integers where all the values are greater than zero. The default value of one will produce a scalar output.

Arguments

alpha	in	The alpha parameter
		Allowed:	double
		Default:	1.0
beta	in	The beta parameter
		Allowed:	double
		Default:	1.0
shape	in	Shape of the output array
		Allowed:	integer or a vector of integers
		Default:	1

Returns
A floating point scalar or array.

Example

      include 'randomnumbers.g'
      rand := randomnumbers();
      numbers := rand.weibull(1.5, 8, 12);
      rand.done()

This example will calculate twelve weibull random numbers, storing the result in a vector.
