	<description>
		Base class for all non built-in types. Everything which is not a built-in type starts the inheritance chain from this class.
		Objects can be constructed from scripting languages, using [code]Object.new()[/code] in GDScript, [code]new Object[/code] in C#, or the "Construct Object" node in VisualScript.
		Objects do not manage memory, if inheriting from one the object will most likely have to be deleted manually (call the [method free] function from the script or delete from C++).
		Some derivatives add memory management, such as [Reference] (which keeps a reference count and deletes itself automatically when no longer referenced) and [Node], which deletes the children tree when deleted.
		Objects export properties, which are mainly useful for storage and editing, but not really so much in programming. Properties are exported in [method _get_property_list] and handled in [method _get] and [method _set]. However, scripting languages and C++ have simpler means to export them.
		Objects also receive notifications ([method _notification]). Notifications are a simple way to notify the object about simple events, so they can all be handled together.
