## Description
<section id='description'>
Write a generalized version of <a href="http://rosettacode.org/wiki/FizzBuzz">FizzBuzz</a> that works for any list of factors, along with their words.
This is basically a "fizzbuzz" implementation where the rules of the game are supplied to the user. Create a function to implement this. The function should take two parameters.
The first will be an array with the FizzBuzz rules. For example: <code>[ [3,"Fizz"] , [5,"Buzz"] ]</code>.
This indcates that <code>Fizz</code> should be printed if the number is a multiple of 3 and <code>Buzz</code> if it is a multiple of 5. If it is a multiple of both then the strings should be concatenated in the order specified in the array. In this case, <code>FizzBuzz</code> if the number is a multiple of 3 and 5.
The second parameter is the number for which the function should return a string as stated above.

  rules.forEach(function (e) {
    if(num % e[0] == 0)
      res+=e[1];
  })

  if(res=="){
    res=num.toString();
  }

  return res;
}
