Job relations in routing

In this example we will show you how to use job relations. Job relations are defined on jobs. They can be used to
express different links between jobs:

SEQUENCE: the jobs need to be visited in the given order
DIRECT_SEQUENCE: the jobs need to be visited in the given order, one after the other
SAME_TRIP: the jobs need to be visited in the same trip, the sequence does not matter
SAME_TIME: the jobs need to be visited at the same time, the assigned resource will obviously be different
PICKUP_AND_DELIVERY: the jobs need to be in the same trip and the pickup needs to happen before the dropoff. (special case of job relation)
SAME_RESOURE: the jobs need to be visited by the same resource (could be another day)
