- Fix StringParser for failed conditions and minor optimizations
- Add tests for StringParser error conditions
More medium-level and minor optimizations:
- no more ParseNode for match tree, use match collection directly (in lieu of accessing parser hierarchy for debugging)
- CharParser is no longer defaulted to add errors
Update JsonGrammar to use StringParser for more speed
- Update speed test to measure warmup speed for initial parse
- sample json now includes an escaped string for testing
Update nuspec & readme for new performance numbers
