Task #145 - Shorten by words

Implement the function shortenByWords(s, n).

It should accept a string, and a number.
It should return the new string that consists of maximum n characters of the original string.
If you have to cut off some chars, place ... in the end.

You can’t cut in the middle of the word, so the result should include only the full words.
So, shortenByWords(‘this string is too long to fit our ad’, 21) returns this string is too...
