Parameter	Value
Inputs:	y0 (half of electrode gap at x=0)
	xm (width of critical area)
	δm (allowed deviation in E over critical area)
	δd (allowed depression in E at x=0 for compactness)
	Δy (electrode thickness)
Outputs:	k		<-- Note:  You can change k manually and then v and vm will be updated.
	νm (v for maximally flat electrode)
	ν (v for compacted electrode)
