AttributeDict (ANTLR 4 Tool 4.13.2 API)

java.lang.Object
- org.antlr.v4.tool.AttributeDict

```
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.
