Important Update: (incomplete)

- Implemented JSON type NULL
- Implement dynamic buffer
- Split parsing int separate re-usable methods
- Implement basic parsing of an object
- Add GetError() method
- Add SkipWhiteSpace as inline method
- Make parsing variable private attributes
- Improve checking when getting parameters
