 * /getCounty - Prompt user for a county name.
 *
 * This dialog will prompt for a county name and then try to validate the county within the jurisdiction country and state.
 * If the county unambiguously validates, then we move on. If it validates as a partial match (e.g. when the user enters
 * "ColXlin" and Google finds "Collin", prompt the user to verify that's the county he or she wanted. If the county
 * cannot be found at all, the tell the user that wasn't even fucking close and reprompt.
