aoe2 role handout distribution program

package main;
import javax.swing.*;

/**
 * This script reproduces the method aoe2 uses to handle roles with "chance" triggers for players
 * We divide an amount of roles that equal to the amount of players and choose the chance for each player.
 * Each player can only get 1 role in every scenario.
 * The program shall then tell us how much times each player got a certain role, after iterating scenarios X times.
 * We can then keep tweaking the chance numbers until we get the deviation we require, using The law of large numbers.
 *
 * The program will show you exactly what will be the distribution of roles depending on the chances you give to each trigger
