Extend manufacturer field by brand

You already know the dropdown "Manufacturer", but what if a manufacturer has different brands?
Many retailers solve this by entering the brands instead of the manufacturer.

But: Google Shopping expects BOTH the manufacturer AND the brand!

With this module you get a new menu item "Brand", where you can create brands and assign them to a manufacturer. When you create an article, you first select the manufacturer and then automatically receive a selection of the brands of this manufacturer.

The trade mark is then also displayed in the frontend under the manufacturer.
