Detailed Description

Demonstrates two modes of back referencing.

"universal" mode - The back reference matches the last of all previously matched phrases regardless of where on the parse tree it occurred.
"recursive" mode - The back reference matches the previously matched phrase which has the same recursive rule parent node.
