inclusion+description

Cards can include other cards inside them.  Inclusion has many benefits:

• Edit inclusions in place, making them 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 card in different ways using inclusion views.  Eg, closed view let you use space more efficiently.
• Specify content patterns with inclusion-based formats.
