bug in assert, comment out write

- commented out an assert
- commented out writing probabilities to the output file, as it
interferes with the logging at each "interval" of time
bug in amount

Each food agent was essentially infinite, which allows prey to always
find food.  Changed amount of each agent to 1 instead of 1000.
reproduction issues

The number of agents in the system balloons. This is the first attempt
to fix that.  It requires agents to have eaten within lastMealLow time
to reproduce.
reproduction issues

The number of agents in the system balloons. This is the first attempt
to fix that.  It requires agents to have eaten within lastMealLow time
to reproduce. It also increases the hungerDeathMod to 2, so that they
prey death rate doubles each step it hasn't eaten.
random cycling

The random number generator built in to MASON is known to not be as
random in the earlier numbers, so a loop was added to start to cycle
through the first 6000 numbers.
modify output

Output was modified to not be divided by interval, as that analysis
could be done later if we have the original values.  Also, a .flush was
added so that everything is written to the file each interval, as
otherwise you have no data if it crashes or the run has to be killed.
