Detailed Description

This is an abstract base class for any elements of a drag and drop form.

This can either be a container which will be represented on the screen as a tab widget or a collapsible group box. Or it can be a field which will then be represented based on the QgsEditorWidget type and configuration. Or it can be a relation and embed the form of several children of another layer.
