A pcb-material definition represents a material in a pcb-stackup layer.


pcb-material material-identifier : 
  name:        String 
  description: String 
  type:        Conductor|Dielectric
  dielectric-constant : Double


The name field is an optional name associated with the material that is different from its identifier.

The description field is an optional string describing the material.

The type is either Conductor or Dielectric, representing what kind of material this represents.

The dielectric-coefficient is an optional double value representing the permittivity of the material.
