- Update printing: Do not use '\n' if indent = 0
- Implement refilling of buffer (from fd) while parsing
- No longer use LineMark, but keep track of char position with CharNo
- Use Mark to reference point for shifting buffer on refill
- SkipWhiteSpace no longer inline method
- Refill buffer if required, change Mark & CharNo on line break
- CreateBuffer(), RefillBuffer() & FreeBuffer() now public methods
- Make Loading and Saving more flexible:
- Refactor from LoadFromFile():
ReadFromFile(), ReadFromHandle(), ReadFromBuffer()
- Refactor from SaveToFile() & PrintToScreen:
WriteToFile(), WriteToScreen, WriteToHandle()
