Class hierarchy #6
Description
The hierarchy:
Tobject
TeventDispatcher
TdisplayObject
TdisplayObjectContainer
Telement
is not efficient.
First, we should separate components that can have a external content (like panel, tabnav etc).
Telement is only for components that can be use with HTML markup.
TdisplayObjectContainer.js and TdisplayObject.js should have HTML, STYLE etc properties.
