/*! @class SimObject
	SimObject is the base class for all other scripted classes.
	This means that all other "simulation" classes -- be they SceneObjects, Scenes, or plain-old SimObjects
	-- can use the methods and fields of SimObject.
	
	@par Identity
	When we create a SimObject with `::new`, it is given a unique id which is returned by `::new`.
	We usually save the id in our own variables.  Alternatively, we can give the SimObject a name which we can
	use to directly manipulate it.  This name can be set with the `::new` operator or it can be added later.

	@code

	@endcode

	@par Static and Dynamic Fields
	Each subclass of SimObject will provide important fields.  For instance, a SceneObject will have a position,
	scale, etc.  These are known as "static" or "built-in" fields.  Additionally, you can add any number of your
	own fields, for example `myField` or `hitPoints`.  These are known as "dynamic" or "add-on" fields.
	To do so only requires you to access the field directly.

	@code

	@endcode

	Attempting to retrieve a field that does not exist merely returns nothing.  There is no error or warning for this.
	Note that static fields exist for every object of a class, while dynamic fields are unique to any one instance.  Adding
	`myField` to one SceneObject does not add it to all SceneObjects.

	@par Reflection
	We can use "reflection" -- the run-time inspection of an object's methods, fields, etc. -- on SimObjects.  For instance,
	we can ask an object what class it instantiates, what dynamic fields it has, etc.  We can also use this feature to
	call a method on an object even if we only know the string name of the method.

	@code

	@endcode

	The id is provided for you by the simulator upon object creation.  You can not change it

	You can not access the id directly.  That is, you can not access `%%object.id`.

	`id` -- an unrelated field to the actual object's id.

	Now the object can be invoked by this name.
	This is different than tracking an object by a variable, such as `%%myObject` or `$myObject`.
	
	Only one object can have a specific name.  Setting a second object
	with this name will remove the name from the former object.

	Note not to confuse this with the `internalName` which is a name for grouping purposes.

	The existence of command is not validated. If you pass an invalid console method name, the
	schedule() method will still return a schedule ID, but the subsequent event will fail silently.

	To manipulate the scheduled event, use the id returned with the system schedule functions.
