Creational Patterns
    Abstract Factory Creates an instance of several families of classes
    Builder Separates object construction from its representation
    Factory Method Creates an instance of several derived classes
    Prototype A fully initialized instance to be copied or cloned
    Singleton A class of which only a single instance can exist
Structural Patterns
    Adapter Match interfaces of different classes
    Bridge Separates an object’s interface from its implementation
    Composite A tree structure of simple and composite objects
    Decorator Add responsibilities to objects dynamically
    Facade A single class that represents an entire subsystem
    Flyweight A fine-grained instance used for efficient sharing
    Proxy An object representing another object
Behavioral Patterns
    Chain of Resp. A way of passing a request between a chain of objects
    Command Encapsulate a command request as an object
    Interpreter A way to include language elements in a program
    Iterator Sequentially access the elements of a collection
    Mediator Defines simplified communication between classes
    Memento Capture and restore an object's internal state
    Observer A way of notifying change to a number of classes
    State Alter an object's behavior when its state changes
    Strategy Encapsulates an algorithm inside a class
    Template Method Defer the exact steps of an algorithm to a subclass
    Visitor Defines a new operation to a class without change
