    Not sure where else it could go. I copied (shamelessly) from an example I found online while re-reading about JavaCC. With this main method, you can run the grammar in Eclipse, and in the Eclipse Console it will be waiting for a String+LFLF (two break lines IIRC).
    
    Then it will use the grammar to parse the string and will output the QueryUnit. I found it useful for reviewing the changes without running some extra class with a main method, or Fuseki.
    
    What do you think? I'm OK with removing it, or moving it somewhere else. Just don't know where else it could go :-)
