@abstract widget that shows one row of tabs and an other row with the eTemplate of the selected tab
@discussion see the example in 'etemplate.tab_widget.test' (use show to view it)
@discussion This widget is independent of the UI as it only uses etemplate-widgets and has therefor no render-function
