StoreQueryOptions

The query settings a store's queries are opened with: indexDdl, how the indexes the Manifest declares are managed, the ddl of the store (wow.stores.<name>.ddl, else wow.ddl). A backend's own query settings, such as MongoDB's read preference, are options of its store (me.ahoo.wow.spi.store.StoreProvider.options).

Fields may be added: the host builds it, so the constructor is internal to Wow; a provider's test builds one with of.
