 Global ids (or UUIDs) provide refetching & global identification for Relay.

+Use `GraphQL::Relay::GlobalNodeIdentification` helper by defining `object_from_id(global_id, ctx)` & `type_from_object(object)`. Then, assign the result to `Schema#node_identification` so that it can be used for query execution.

 ## Todo
 
 - `GlobalNodeIdentification.to_global_id` should receive the type name and _object_, not `id`. (Or, maintain the "`type_name, id` in, `type_name, id` out" pattern?)
-- Make GlobalId a property of the schema, not a global
 - Reduce duplication in ArrayConnection / RelationConnection
 - Improve API for creating edges (better RANGE_ADD support)
 - If the new edge isn't a member of the connection's objects, raise a nice error
 - Rename `Connection#object` => `Connection#collection` with deprecation
