Singleton Design Pattern: Ensure a class has only one instance and provide a global point of access to it. (Gamma et al, Design Patterns)

Responsibility Singleton:

• Defines an Instance operation that lets clients access its unique instance. Instance is a class operation.
• Responsible for creating and maintaining its own unique instance.
