connector model interface and internal implementation added
- connector model seems to be almost complete 
- persistance and skin still missing
TODO persistance, Skin, connect(..) & tryConnect(..)
STILL TODO persistance, Skin

connect(..) & tryConnect(..) done
we probably need a propert node controller: started implementation, node sik is responsible for drawing connectors
compiles and runs again (connections are corrently broken, connector ui still missing)
started io implementation
