`CacheIsKing` is a simple cache that allows you to store any item, including objects, pure Swift structs, enums (with associated values), etc. Simply put, it's designed to act like an `NSCache` for everything, including Swift variables. `CacheCreek` provides an an LRU cache that allows you to store any item, including objects, pure Swift structs, enums (with associated values), etc. Simply put, it's designed to act like an `NSCache` for everything, including Swift variables.
