    //TO-DO - create the following 3 classes

    //* Motorcycle

    //* Car

    //* Truck

    //...and any more extra classes as necessary to create an ideal class structure that will fulfill the following criteria:

    //* All 3 classes must implement interface IVehicle

    //* All 3 classes must have a name passed in at construction, that then cannot be changed

    //* When the Specs function is called on any Vehicle, it should get passed into the function GetSpecsStringForVehicle() and the result should be returned

    //* The LoadCargo setter should check the size and weight of the cargo and then:

    //IF either the size OR the weight of the cargo is greater than the capacity of the vehicle, then call Cargo.ReportLoadingAttempt, pass in succeeded = false and then make no changes to the vehicle

    //ELSE assign the cargo value to the vehicle and call Cargo.ReportLoadingAttempt and pass in succeeded = true

    //* The LoadCargo getter should return the current cargo value loaded on the vehicle (i.e. the last cargo that was successfully assigned using the setter)

    //*** Motorcycle Class: ***/

    //CONSTRUCTOR: Motorcycle(string name)

    //All motorcycles will have 2 wheels, 0 doors, 1 seat and have a max cargo capacity of Weight 10, Size 10

    //*** Truck class: ***/

    //CONSTRUCTOR: Truck(string name, int wheels)

    //All trucks will have 2 doors, 3 seats and a max cargo capacity of Weight 1000, Size 1000.

    //Trucks can have different numbers of wheels, specified upon construction and cannot be changed afterwards.

    //The number of wheels cannot be less than 4

    //If less than 4 wheels are specified, throw an Exception with the message "Trucks can't have less than 4 wheels"

    //*** Car class: ***/

    //CONSTRUCTOR: Car(string name, int doors, int seats, int maxCargoSize, int maxCargoWeight)

    //All cars have 4 wheels, but all others aspects of a car (doors, seats and max cargo capacity) can be defined on construction (but then cannot be changed afterwards)

    //Cars cannot have more than 7 doors (otherwise throw Exception: "Number of doors specified too much for any car")

    //Cars cannot have more than 10 seats (otherwise throw Exception: "Number of seats specified too much for any car")

    //No car can have a cargo capacity of more than Weight 100 or Size 100. (If either is specified as too big, throw Exception "Max cargo size or weight specified too big for any car")

    //Once all the classes have been created as specified above, the task is complete when the program is run and the output produced matches the comments below each vehicle test
