PHP Class Cachearium\Backend\CacheRAM

It's a very simple implementation. It's reasonably inneficient because it a 3-level array, but it does invalidation correctly. This is useful for data that is loaded many times in one execution but which may change constantly, or in servers that have no external cache support for a quick speedup.
