/**
 * Parking a bike edge.
 * 
 * Note: There is an edge only in the "park" direction. We do not handle (yet) unparking a bike, as
 * you would need to know where you have parked your car, and is probably better handled by the
 * client by issuing two requests (first one from your origin to your bike, second one from your
 * bike to your destination).
 * 
 * Cost is the time to park a bike, estimated.
 * 
 * Bike park-and-ride and "OV-fiets mode" development has been funded by GoAbout
 * (https://goabout.com/).
