SchemaObject::canonical_path_info

[rbalicki2]

• Given a root type for a selection set, how do we write an operation text for that? How do we write a reader artifact? How do we write a normalization AST?
• Root types should generate something like query FooQuery { ...selection_set }
• Types that implement node should generate query FooQuery($id: ID!) { node(id: $id) { ... } }
  etc.
