Automatically add Related ListViews to Detail View

[nathanclevenger]

Prioritize _detail.lists in #5 but we should be able to auto-detect if there is a relationships

This is specific to reverse lookups of 1-to-Many relationships

figured out sublists within a detail view... slight but in Customer detail _lists... currently pointing to Orders rather than I believe Sales Order

[crisner1978]

Fixed Customer sublist. Changed graphdl.yaml Customer._detail._lists - [SalesOrder]

Category & Customer are the only ones with Sublists explicitly defined, but if you look at the Schema you should be able to see all of the relationships ... and we want to detect sublists for all of those ... so all of these should have sublists:

Categories -> Product
Customer -> Sales Order
Employee -> Employee Territory -> Territory
Employee -> Sales Order
(Employee Territory and Order Detail are both sub-categories, so they should be hidden - I'll figure out the syntax for that)
Product -> Order Details -> Order
Region -> Territories
Shipper -> Sales Order
Supplier -> Products -> Order Details -> Sales Orders
