Changes:
- A connection between two nodes get updated once per cycle
- Nodes have a type specified in sparktech_energy_conductor as follows
1 for a transfer node like cables
2 for a producer like solarpanels
3 for a storage like capacitors
4 for a consumer like electric furnaces
- Nodes of type 2 balance between each other and push to all other nodes
- Nodes of type 1 and 3 balance between each other
- Nodes of type 4 pull from all other nodes that are not of type 4
- When balancing, the relative charge of a node is concidered
