Market is a greatly simplified model of a stock market. For more
details, please see http://www.santafe.edu/projects/swarm/examples/market/

Market is an example of a previous bit of simulation code that was
quickly hacked to work under the Swarm framework. There's only one
object being simulated, the "market" - the code there is a stub to the
original simulation code. We only use Swarm's facilities for inputting
parameters and displaying data. It also happens to be a simulation
that doesn't take place in a 2d grid.

To have some fun with this, set the "scale of dividend jumps" up at
about 10.0 or so.
