Container is the base class for all frame types. It provides the basic structure and functionality for all frame objects. Container objects can contain other container objects, thus forming the foundation for the hierarchy of frame objects.

In addition to the Object and VisualObject methods, container objects have the following methods:

addChild	Adds a new object to the container
getChild	Returns an object in the container by its ID
getDeepChild	Returns an object in the container or its sub-containers by its ID
removeChild	Removes an object from the container by its ID
removeChildren	Removes all children object's
updateZIndex	Updates the Z-index of an object in the container
setImportant	Marks an object as important, so it is displayed on top if needed
sortElementOrder	Sorts the order of elements in the container based on their Z-indices
clearFocusedChild	Removes focus from an object in the container
setFocusedChild	Sets focus on a specific object in the container

A Container Object inherits from VisualObject, but won't draw children objects.
