Detailed Description

Structure to contain a directory cache entry.

---

For performance, a cache of the last Burger::Filename::kDirectoryCacheSize MacOS directories are stored with their Directory IDs and volume reference numbers. Since these number can ba invalidate when a directory is deleted or created, any call to a Burgerlib function that performs that action will also purge this cache.

When a Burgerlib path is parsed, a Directory ID and Volume Reference needs to be generated. If the directory exists in the cache, the values found here will be used. If not, it will be determined and added to the cache.
