Use STL and C++14 to return a dynamically created string from a function/method, that is automatically garbage collected.

What I want to show here is not a new or surprising trick, but simply the consistent use of the possibilities available since C++14 to use a "clean" memory management for the return of dynamically allocated memory. The main use case are certainly strings. My string class serves here only as an easy to understand example to explain the approach.
