```python
""" FizzBuzz
Rules:
	Make a function that prints a range of numbers (1-100 by default)
    If the number is:
        a) a multiple of 5, print 'Fizz'
        b) a multiple of 7, print 'Buzz'
        c) a multiple of 15, print 'FizzBuzz'
    Otherwise, print the number.

    Example output (1-20):
    1
    2
    3
    4
    Fizz
    6
    Buzz
    8
    9
    Fizz
    11
    12
    13
    Buzz
    FizzBuzz
    16
    17
