Title: Created a StringUtil and simple examples about it

Hildeberto,

I created a StringUtil.
I looked that is very common this code:
string == null || string.isEmpty();

I prefer send this code into a Util.
I looked too a good oportunity of the new members send PR, because is necessary alter this in more files.
