Detailed Description

A simple wrapper class that converts all the passed cache keys into a prefixed notation: "key" -> "prefix/key".

This wrapper is usually needed when handing embedded objects using the same cache storage, e.g. masking brush preset, which is stored inside a normal preset under a prefix ("MaskingBrush/Preset/")

store a cached object value into the cache using key WARNING: storing an object twice with the same key is considered as invalid operation and will assert! This behavior is intentional to avoid cache key aliasing.
