Maintains a cache of friends that can recieve application requests from the user in using the frictionless feature of the requests web dialog.
This class follows the FBCacheDescriptor pattern used elsewhere in the SDK, and applications may call
one of the prefetchAndCacheForSession methods to fetch a friend list prior to the
point where a dialog is presented. The cache is also updated with each presentation of the request
dialog using the cache instance.
