Managing Expiration for Cache Directories

Bioconductor version: Release (3.19)

Implements an expiration system for access to versioned directories. Directories that have not been accessed by a registered function within a certain time frame are deleted. This aims to reduce disk usage by eliminating obsolete caches generated by old versions of packages.
