Attribute (PFL Dynamic 4.0.1-b002 API)

```
public class Attribute<T>
extends Object
```
Class used to define dynamic attributes on AttributedObject instances. Note that T cannot be a generic type, due to problems with Class when T is a generic. To work around this problem, simply create an interface that extends the generic type (you are programming to interfaces, right?).
