AttributeDict (ANTLR 4 Tool 4.0-rc-1 API)

```
public class AttributeDict
extends Object
```
Track the attributes within retval, arg lists etc... Each rule has potentially 3 scopes: return values, parameters, and an implicitly-named scope (i.e., a scope defined in a rule). Implicitly-defined scopes are named after the rule; rules and scopes then must live in the same name space--no collisions allowed.
