@merrimanr @nickwallen @justinleet - I just want to be sure that I'm
following this correctly. This particular callback appears to be a synchronous,
blocking callback. The crux of the implementation is that you're passing in a
function pointer to be executed when the parsing either succeeds or fails in
order to decouple the parsing logic from Storm itself (e.g. tuples, etc.)?---
