Early preview(2)

My new visual programming environment.

- Macro (under developing)
- Node definition in Python (callback based)
- Code editor
- Node template
- Visual debugger (It's fun to see how node networks are working. I'll soon add a video on this entry)

See some brief descriptions here about the demo.
