+/**
+ * The spot scene model extends the standard scene model with information
+ * on locations, clusters and portals. Locations (and by extension,
+ * portals) are referenced by a globally unique identifier so that portals
+ * can stably reference the target location in the scene to which they
+ * connect. The scene repository is responsible for assigning this unique
+ * identifier. Clusters are tracked by index rather than unique
+ * identifier, but only exist as an attribute of locations (a location
+ * belongs to zero or one clusters).
