Thanks for the prompt answer, Sean.
I will attempt to use existing libraries then, and will see how that goes.

I'm not sure how I would go about transforming uniform distribution
random numbers to a specific distribution...I could do it for simple,
streight-lined artificial distributions, but for distributions like
gamma, it'd turn into a project of it's own...

Thinking about it, it seems to me that it would be good enough to
track down one or two good libraries supporting a wide variety of
probability distributions and do the following:
- package them together with mason if the licences are compatible and/or
- update the mason documentation so that it links heavily to the
selected libraries and explains how to use them
This would have the following benefits:
- is relatively easy to do
- would make it clear to mason users that this is the recommended way
to generate random values according to a specific distribution
- would spare users the burden of having to search for good libraries
themselves
To that effect, when I'm done with my project, I can provide a short
summary about my experiences and you might be able to use that for a
start.
Cheers,
Tomislav
