Completed data collection for multiple sample sizes in a single sampling pass.  Simulations have good performance.  400 individuals with 6 loci takes 98 seconds and does three sample sizes + population statistics.  100 individuals with 2 loci takes 41 seconds -- all numbers refer to 2MM steps.

Need to figure out a good relation for "desired number of copies" turning into the length of the simulation given population size, number of loci.
