* added test cases to test the ``AmiiboService` locally;
* conformed the models to the `Hashable` protocol;
* documented the use of caching with the `AmiiboService` service;
* updated the reference to the new AmiiboAPI url;
* updated the year on the copyrights and header files;
* updated the overall documentation of the source code and the package.
