PrecacheApi (Class)
Namespace: Wrld.Precaching
API to allow users to precache areas of the map for later use. When a map resource is first downloaded it is added to a cache from which it will be retrieved if it is later requested again. This API allows users to request all resources for a given area, priming this cache and avoiding the need to redownload these resources.
