 This is a model of an autonomous supermarket where agents have the task to move items around, perhaps pick some items from the inventory and drop the items at a till where a customer can collect them.
 
 The scenario is consist of number of agents who can move around by a car and pick limited number of items and drop the items at a location.
 
 durative actions used in the domain:
-- ```durative-action *pick*```: the agent can pick an item if they are at the same location and number of items that the agent is carrying is less than their capacity.
-- ```durative-action *drop*```: the agent can drop the items at a location and this result in decreasing the number of items they are carrying.
-- ```durative-action *movecar*```: the agent can move from a point to another with a car once they get on the car.
-- ```durative-action *getoncar*```: the agent can get on a car if there is no other agent on it.
-- ```durative-action *getoffcar*```: the agent can get off a car.
