Base class from which CacheDescriptors derive, provides a method to fetch data for later use
Discussion:
Cache descriptors allow your application to specify the arguments that will be later used with another object, such as the FBFriendPickerViewController. By using a cache descriptor instance, an application can choose to fetch data ahead of the point in time where the data is needed.
