A previous commit allowed maps to use attributes in the parent collection for boundaries or points, but at the cost of preventing child collection attributes from being used. We fix this by not going on to look for parent attributes if we find a child attribute.
Pass along the caseName property of collections. Use it to change the display of summaries in a collapsed case table. So, for example, "a bag of 52 MnMs."
