/***
* Meta Widget
* @extends widget
* @tag metawidget
* @screenshot An example of a metawidget with two inner widgets. The metawidget is not in itself visible.
* <metawidget layout="vbox" name="dims" format="''" storechildren="true">
* <lineedit name="test1" value="test"/>
* <checkbox name="test2" value="ja" truevalue="ja" falsevalue="nej"
* caption="Og svaret er?"/>
* </metawidget>
* @container
* This widget is simply a container compositing its value from the widgets
* within it. The value of the widget cannot be set and its value attribute is
* therefore ignored.
* @example An example of how to use metawidget with two inner widgets:
* <metawidget layout="vbox" name="dims" storechildren="true"
* format="return widget('test1'):value() .. ': ' .. widget('test2'):value()">
* <lineedit name="test1" value="test"/>
* <checkbox name="test2" value="ja" truevalue="ja" falsevalue="nej"
* caption="Og svaret er?"/>
* </metawidget>
* @att layout the layout of the widget. Can be one of 'vbox' or 'hbox'.
* @att storechildren This attribute indicates wether the child widgets should
* be stored on macro commit. It can be either 'true' or 'false'.
* @att format This attribute contains lua code. The return value of the code
* is the resulting value of the meta widget.
* @att layout The layout assigned to the widget. Can be one of 'hbox' or
* 'vbox'.
