Joose provides a standard role to build singletons. Just use does: [Joose.Singleton] in a class definition to declare your class to be a singleton. Your class will receive a clas method getInstance() that returns the instance. You will no longer be able to create instances with the new operator.

Example

``` Class("MySingleton", { does: [Joose.Singleton],

    has: {
        test: {
            init: function () { return [] }
        }
    }
})

var single = MySingleton.getInstance();

```
