Right now, in the image there exist two ways to annotate an AST:
�- the Opal way
�- the RB Way

We should simplify that by having only one. So far, the only user of the RB bindings is the ASTInterpreter + the RB tests.

So, I prepared a slice and issue [1], with the following details

- annotate ast using opal annotator
- extended OCBindings to read and write from an AST interpreter
- not yet made a difference between arg nodes with a different class (just put an if)
- i didnt add inst vars into the opal bindings for the binding->node relation as in RB, I send the node as a parameter
- I had to adapt the #compile: into ASTInterpreter because
� � - opal does not annotate other than method nodes
� � - undeclared variables raised warnings, not errors

There is one problem yet,�I have only one failing test: #testEnsureTricky. I don't understand yet why it is failing and debugging it is pretty complex :). So any help is welcome in reviewing the changes.
