// DESCRIPTION
// Counting from 0 to 100, print out each number in the console.

// RULES
// 1. If the number is a multiple of 3, print "fizz" instead of the number.
// 2. If the number is a multiple of 5, print "buzz" instead of the number.
// 3. If the number is a multiple of both 3 and 5, print "fizzbuzz" in place of the number.
// 4. Otherwise just print the number itself.
// 5. Each entry should be printed on a new line.
