Requesting a reverse direction isoline

Isoline can be calculated in the reverse direction. It answers the question: From where can I get to the destination within given range. This can be for example useful to determine which vehicles from a fleet of vehicles (Taxi service) can get to the destination within given time. To trigger calculation in reverse direction, use destination parameter instead of start.
