    Given a non-empty string and an int N, 
    return the string made starting with char 0, and then every Nth char of the string. 
    So if N is 3, use char 0, 3, 6, ... and so on. N is 1 or more.
  
  Examples
  
    everyNth('Miracle', 2) → Mrce
    everyNth('abcdefg', 2) → aceg
    everyNth('abcdefg', 3) → adg
