docs: Tests if this user can create Activities.
          A return of true does not guarantee successful authorization. A
          return of false indicates that it is known creating an Activity
          will result in a PermissionDenied. This is intended as a hint
          to an application that may opt not to offer create operations to
          an unauthorized user.
          return: (boolean) - false if Activity creation is not
                  authorized, true otherwise
          compliance: mandatory - This method must be implemented.
