I am not too familiar with this...maybe someone will correct me.

I think this uniformIntRand distribution uses a built-in random number 
generator called Globals.env.randomGenerator. It is an instance of 
SimpleRandomGenerator, the MT19937.

According to the documentation set, SimpleRandomGenerator inherits 
methods from BasicRandomGenerator, which includes "setStateFromSeed". 
You should be able to set the seed using:

Globals.env.randomGenerator.setStateFromSeed (anInteger);

Somewhere (in the old email archives?) you can find examples of using 
the current clock time etc. as the value of (anInteger).
