ReportError() public method

Report a recognition problem.

* This method sets errorRecovery to indicate the parser is recovering * not parsing. Once in recovery mode, no errors are generated. * To get out of recovery mode, the parser must successfully match * a token (after a resync). So it will go: * * 1. error occurs * 2. enter recovery mode, report error * 3. consume until token found in resynch set * 4. try to resume parsing * 5. next match() will reset errorRecovery mode * * If you override, make sure to update syntaxErrors if you care about that. *
