ITT #10: Understanding OOP

NOTE: This comment by Cal Evans pointed out an oversight on my part regarding naming conventions for classes. To avoid conflicting with other classes, names should be distinctive, and as such, I changed the name of the example class from "date" to "Ennui_Date".

Recently, I've fielded a handful of questions concerning object-oriented PHP. What is it? How does it work? Why should we care?
