PINCache

Uses Grand Central Dispatch (GCD) to ensure safe parallel access from multiple threads, fixing deadlocking issues present in the original TMCache fork, as stated in the README.

Combines PINMemoryCache for fast in-memory access and PINDiskCache for persistent storage, allowing objects to be immediately available in memory while written to disk in the background, coordinating both caches efficiently.

On iOS, the memory cache automatically clears itself on memory warnings or when the app backgrounds, helping prevent crashes and improve performance without manual intervention.

Can store any object conforming to NSCoding, including collections like NSArray, with efficient archiving that avoids duplication on disk, as demonstrated in the README examples.
