The Wrap Return Value refactoring allows you to select a method, and either create
a wrapper class for its return values, or use an existing, compatible wrapper class. All returns from
the method selected will be appropriately wrapped, and all calls to the method will have their returns
Wrapping a method's returns are useful, if your design changes in such a way that you want a method to
return more information than originally planned. After wrapping, the wrapper class can be extended, allowing
more data to be returned from the method. Also, it is common to wrap primitive return values,
thus allowing interface and implementation to be decoupled as needed.
