    Default my program. Random number generater.

    my program first says:

    As we know if you could only pick a number
    out of 1 million your chances are 1 in 1 million:
    today I am going to prove this...I hope

    you can pick a number from 2 to 10000000000000000000 ish <-- this is the number Range
    then you pick a number you want to come up
    and how many times you wish for it to occur
    password is abc123... incase you can't find it

    bug free i hope
