1/** This random number generator using your
2   own computer time to generate random
3   number, the program is working so quick
4   so you can't use a for loop to generate
5   multiple numbers. even with a delay the
6   program will run in a small jumps from
7   number to another so the only way to
8   properly generate random numbers is
9   running the code multiple times         **/
