• Examples.WheelBasedCraneCrab: fix typo in the example name (previously WheelBasedCranCrab).
• VehicleComponents: add Wheels.BaseClasses to collect common wheel's elements.

New components:

• VehicleComponents: Air drag model for vehicles.

Obsolete components:

• Types Color and SpecularCoefficient are obsolete and will be deleted in the next major library release. Corresponding types from Modelica.Mechanics.MultiBody.Types are used instead.
