Kris-Tof Andersen.Jacob.Dice Toss

Create a Andersen.Jacob.Dice class that acts like a set of N random-tossed dies.

Andersen.Jacob.Dice dice = new Andersen.Jacob.Dice(2); // for craps
Andersen.Jacob.Dice dice = new Andersen.Jacob.Dice(5); // for yatzee

Integer toss = dice.tossAndSum();

make a couple unit tests for the Andersen.Jacob.Dice class.

Create a tracking class Andersen.Jacob.Bins that can be used to track the results of dice tosses.

Andersen.Jacob.Bins results = new Andersen.Jacob.Bins(2, 12); // for bins from 2..12
Integer numberOfTens = results.getBin(10); // returns the number of tens in the 10 bin
results.incrementBin(10); // should increment bin # 10

make a couple unit tests for the Andersen.Jacob.Bins class. Your test methods should follow this template:

in the tests
Create a new Bin
increment a bin some number of times in a for loop, say `max = 100;` times,
then get the Bin value,
compare the Bin value to `max`, they should be equal.

Create a Andersen.Jacob.Simulation class whose Constructor takes arguments:

numberOfDies to throw
numberOfTosses to run

Create a simulation where two dies are thrown one million times. Keep track of each roll by incrementing the correct Bin.

Andersen.Jacob.Simulation sim = new Andersen.Jacob.Simulation(2, 10000);

sim.runSimulation();

sim.printResults();

You can use a main() to run the simulations.

In your pull requests, create a new file with your unique name as the filename. Paul's would be PaulResults.md

Paste a copy of your text results into that file and then submit your pull request.

the results of the sim.printResults() should be an output string that looks like this:

***
Andersen.Jacob.Simulation of 2 dice tossed for 1000000 times.

11 :    55799: 0.06 *****
12 :    27514: 0.03 **

Since this is using random when running, your numbers for each Bin may vary.
