Base class for all objects Unity can reference.
Any public variable you make that derives from Object gets shown in the inspector as a drop target,
allowing you to set the value from the GUI.  UnityEngine.Object is the base class of all built-in Unity objects.
Although Object is a class it is not intended to be used widely in script.  However as an example
Object is used in the Resources class.  See Resources.LoadAll which has [[Object[]]] as a
return.
