Flexi-FizzBuzzBazz

Flexi-FizzBuzzBazz generates a list of items representing the consecutive sequence of integers from start to end. When the integer is a multiple of Fizz, the string "Fizz" is added instead. Likewise, for multiples of Buzz, "Buzz" is added. For multiples of both Fizz and Buzz, "FizzBuzz" is added.

If the optional "Bazz" value is given, then "FizzBuzz" becomes "FizzBuzzBazz" for items that meet the optional condition.
