Returns the probability distribution function OR the cumulative probability function for a weibull distribution.

x	The numeric value at which to evaluate the function.
alpha	The first parameter.
beta	The second parameter.
cumulative	A logical value indicating the type of function to use: False (or 0) = individual probability (equal to) True (<> 0) = cumulative probability (equal to or less than)

* The weibull distribution is a continuous distribution
* If "cumulative" = False, then the height of the curve at "x" is returned.
* If "cumulative" = True, then the area under the curve to the left of "x" is returned.
* This function was added in Excel 2010 to replace the WEIBULL function.
