Thanks Nate Soares!

Yeah the page is still under development and I'm planning to add more negative examples as I go along. It was just copy-pasted from the Isomorphism: Intro (Math 0) page to have something here to start.

Do you feel the isomorphism page should have more negative examples for bijections? Or that it's long enough already?
