Caching Manager in Sitecore 8.2+

I'm a huge fan of Mark Stiles' Caching Manager Module as a tool to use for tuning caches (and Mark has a great writeup of how to use it here). However, when throwing it at a Sitecore 8.2 Update 2 instance recently, I found it didn't work. The culprit? Sitecore changed a lot of the cache objects to interfaces.

I hacked together a version that works for folks using 8.2 and higher, that you can use in the interim. Hope it helps someone!
