Class Singleton

Description

«abstract» Singleton

To create a Singleton class, simply add "extends Singleton" to your class definition and add $this->checkSingletonConstraint() as the first line in your constructor.

Note: this class is abstract, because it extends an abstract super-class without implementing all abstract functions - NOT because it declares any abstract members itself.
