* Simple string wrapper.
*
* wibble::text::Wrap takes a string and splits it in lines of the give length
* with proper word wrapping.
*
* Example:
* \code
* WordWrap ww("The quick brown fox jumps over the lazy dog");
* ww.get(5); // Returns "The"
* ww.get(14); // Returns "quick brown"
* ww.get(3); // Returns "fox"
* // A line always gets some text, to avoid looping indefinitely in case of
* // words that are too long. Words that are too long are split crudely.
* ww.get(2); // Returns "ju"
* ww.get(90); // Returns "mps over the lazy dog"
* \endcode
