Reproducibility

Initialize random number generator such that results are reproducible. This will make teaching and grading easier.

This has turned out to be trickier than expected. The rand() routine in stdlib isnn't threadsafe, and seems to do some funny stuff under the hood. Although C++ includes a nice API for random number generation, it requires a C++11 compliant compiler, which isn't available on MIT CRPG clusters. I plan to substitute in my own threadsafe LCG class instead in the next few days.

So this has turned out not to be as easy as expected. I think I've reached
a quota on how much PINSPEC I can deal with and need to refocus on my class
and research for a bit. So as long as it's not absolutely necessary right
now, I'm going to put this on my back burner for a while (or Matt or Jon
can take a look at it...)
