Do not allow Car Sharing 1 and Car Sharing 3 to be selectable at the same time.

[awikstrom-ladot]

Overview

Currently, the Calculator allows people to select Car Sharing 1: Car Share Parking and Car Sharing 3: Private Car Sharing Fleet. This results in double dipping, since the applicant will theoretically be getting points for providing the parking and the service itself, which is not the point of Car Share Parking.

Action Items

Grey out Car Sharing 1 or 3 if a user selects one of them.
