       The "after" advice type is used to execute code after a function is called, regardless of whether or not
       the function returned normally or threw an exception.

       The "after" advice type should be used when you need to potentially make multiple different changes to
       the returned value or the thrown exception.

       If you only care about normally returned values you should use "returning" in the pointcut to exclude
       join points occuring due to exceptions.

       If you only care about handling exceptions you should use "throwing" in the pointcut to exclude join
       points occuring due to normal return.
