The rotational inertia of the body, usually in kg*m^2. This can be accessed as a union of PhysicsBody.mass, PhysicsBody.rotationalInertia and PhysicsBody.localCenterOfMass using PhysicsBody.massConfiguration. When this value is overridden with PhysicsBody.massOverride, setting it authors the override value, which persists across mass recalculations.
