Expanded the antenna rule violation setup and calculations to 

include (1) specification of sidewall or surface to use for
each type individually, rather than a single method for all
types, and (2) specification of a linear model R = Ax + B for
the ratio limit when diodes are attached to the wire, where x
is the diode surface area (unitless, as this is a ratio).
