<h2>Overview:</h2>
<pre>This package provides a discrete random number generator.

<b style="color:darkblue">
make-standard-rangen:</b> Make a new random number generator based on a list of
value-density pairs.<b style="color:darkblue">
Example:</b> (rsm.rand:make-standard-randgen
'((1 0.2) (2 0.25) (3 0.25) (4 0.3)))
makes a random generator object that has values 1,2,3,4 with
corresponding probability density values 0.2, 0.25, 0.25, 0.3.<b style="color:darkblue">
clone :</b> Clone a random generator object.<b style="color:darkblue">
next-rand :</b> Get a random number (or numbers) from the a random number object.<b style="color:darkblue">
rand-val-dens:</b> Set the value-density pairs for the random number object.<b style="color:darkblue">
rand-dist :</b> Get the distribution function (array) from a random
generator object.<b style="color:darkblue">
bin-rand :</b> Form an ASCII display that describes the distribution of
the random number object.</pre>
