nesting+description

Cards can include other cards inside them.  nesting helps you:

• edit chunks of content in place - faster and easier than editing whole pages.
• keep data current - a card's updates (e.g., an address or event info) appear everywhere it's included.
• display the same information in different ways using views.  Eg, closed view let you use space more efficiently.
• specify content patterns with inclusion-based formats.
