// EmbeddedRelationAdapter will augment the query object in calls made to
// DS.Store#findRecord, findAll, query, and queryRecord with the correct "includes"
// (?include=relatedType) by introspecting on the provided subclass of the DS.Model.
// In cases where there is no query object (DS.Model#save, or simple finds) the URL
// that is built will be augmented with ?include=... where appropriate.
//
// Example:
// If a model has an embedded hasMany relation, the related type will be included:
// roles: DS.hasMany('role', { embedded: 'always' }) => ?include=roles
