Either<S extends Object?, E extends Exception> class sealed

This abstract class defines the success and failure states. in a Either<Success, Failure> manner. Use in cases where it is necessary to handle errors more explicitly. This is done by implemeting the when method as a pattern matching method. Where the success callback is called if the result is a success, and the failure callback is called if the result is a failure.
