Major update:

- Converted CSocketCore to Class/Object
- Implemented CFunctionCore as base class for CPortCore and CSocketCore
- Moved common functions to CFunctionCore and renamed
  eg. Maintain() -> Process()
- Pass Objects directly to each other as OutputFunction
- New Input() method allows data transfer between objects
