[antlr-interest] ANTLRWorks Interpreter and Debugger diagrams.

[G. Richard Bellamy]

I should have called out the fact that I'm a novice ANTLR user (if it 
wasn't already obvious).

Given the high level of attention and consideration I received 
yesterday, I'm going to go ahead and jump back in. :)

I decided it would be best if I became more familiar with the toolset. 
Thus I put together the most basic arrangement I could think of to test 
the rule I'm trying to understand, and that was to:

1. Create a Combined.g grammar file with a single lexer rule and a 
single parser rule.
2. Target Java so I can easily Interpret and Debug input with ANTLRWorks.

Attached are the results of that attempt. One of my points of confusion 
is the difference in the Interpreter and the Debugger Parser Tree/AST 
diagrams. Could someone help me understand what I'm seeing here? Does 
the Interpreter behave much differently than the Debugger when dealing 
with MismatchedTokenExceptions?

TIA,
-rb
