[#16 ] Now, it's possible to extract the value from an Option<A> and make assertions directly on the object 💯
[#17] It's possible to extract values from an Either<E, A> if right-sided or left-sided. Then, you can make assertions directly on the extracted objects! 👍

🐛 Fixed Bugs

[#18] Change the scope of assertion constructors. Now, you must use the dedicated factory methods 😠!
