//It will remove Honourifics as part of the business requirements if so detected [Mr. or Mrs.].
//It will invert the first name as provided with the surname to give [Smith, John] to an input of [John Smith] and many other variations.
//It will handle the correct removal of padding from the input string not only from the ends of the string but also in between word boundaries.
