FizzBuzz is a Javascript coding exercise program that retrieves two integers from the user.
Creates a list of numbers 0-100. Checks each number to see if it is a multiple of either of the user's inputted integers.
If the number is a multiple of integer "a" then it is replaced with "Fizz", if the number is a multiple of integer "b" then
it is replaced with "Buzz", finally if the number is a multiple of both integers then it is replaced with "FizzBuzz".
