Re: random generator

[Paul Johnson]

If you run the model with the -s flag, the default random generator will 
be started with a value that depends on time. Observe the effect of

./heatbugs -s

If you are using your own random generators, I think the easiest thing 
to do is type in your own seed values at the command line.  That way 
programs that run the sim over and over can directly adjust the seed how 
they like.  In newer editions of Swarm, the -S flag can be used, as in

./heatbugs -S2342123
