+Factory Method
+==============
+
+Purpose
+-------
+
+The good point over the SimpleFactory is you can subclass it to
+implement different ways to create objects
+
+For simple case, this abstract class could be just an interface
+
+This pattern is a "real" Design Pattern because it achieves the
+"Dependency Inversion Principle" a.k.a the "D" in S.O.L.I.D principles.
+
+It means the FactoryMethod class depends on abstractions, not concrete
+classes. This is the real trick compared to SimpleFactory or
+StaticFactory.
