What's in a Node Instance?
Here are some ideas:
o [State]?, which includes:
- Current levels, user-accessible parameters
- Scheduler information relevant to the node.
o The node's name (maybe). Either way, this cannot be accessible by ops, as they could screw things up.
o Node's type ('node.__class__' or somethin'). This is the name of the NodeType? that the nodes were instanciated from.
o PortObjects? with current their values
o Node's operations (a group of functions). See NodeOperations?.
