Detailed Description

Singleton class to manage game config file caching.

It uses paths to config files as key to find correct cache

Todo:

Make smarter filetree checksum caching so only required parts of tree are checked at startup. Trees are overlapping so have to split trees to subtrees to only do check once per file.

Make cache system easily allow validation of in memory cache objects using hash checksum of preproc_map.
