Chapter 3 - Type Trees Exercise
8 Create the Row type. Row is also a group because it represents a complex
data object consisting of other objects.
The Row group type should be on the same level as the Order type. Ensure
the Root type is selected when you create the Row type or move the type.
9 Create the Column type, which is an item type.
10 As subtypes of Column, create the different kinds of columns: Product,
Quantity, and Style.
Your type tree now has all of the types in your data.
