Support for nets

[seveibar]

• Introduce a Net class as a primitive
• nets are automatically created from props, we can create a getPropNetReferences on PrimitiveComponent that can be overridden for classes like Resistor and Capacitor that have custom nets
• Introduce a new renderphase "CreateNetsFromProps"

Here are some pull requests that might be helpful reference for this task:

• Implement nonoverlapping checks, add NetManager system for detecting connected traces, add workflows
• Opaque Groups initial, Rename Project to Circuit, add pullupFor and pullupTo, add decouplingTo and decouplingFor

This might have already been done via: Net Implemenation, PcbRouteNetIslands render phase, rename OpaqueGroup to Subcircuit.
