Focus on within-layer clearances for now.

Any more complex design rules (such as dielectric breakdown through
the layer stack) requires more data than we have in PCB's data-model,
and may actually belong in a separate calculation utility that would
calculate out a geometric design rule that can be applied in PCB.
