Open to Ground
Default Options:

for the purpose of generating a value to pass to the pin)
* gap: '6um' -- The gap of the 'cpw'
* termination_gap: '6um' -- The length of dielectric from the end of the cpw center trace to the ground.
Values (unless noted) are strings with units included, (e.g., '30um')
