## Detailed Description

This class allows to merge several widgets to single one.

It has quite limited functionality and can't merge widgets with different attributes. For instance, if widgetA has color array and widgetB has only global color defined, then result of merge won't have color at all. The class is suitable for merging large amount of similar widgets. :
