-# A set of ri data.
-#
-# The store manages reading and writing ri data for a project (gem, path,
-# etc.) and maintains a cache of methods, classes and ancestors in the
-# store.
-#
-# The store maintains a #cache of its contents for faster lookup. After
-# adding items to the store it must be flushed using #save_cache. The cache
-# contains the following structures:
-#
-# @cache = {
-# :class_methods => {}, # class name => class methods
-# :instance_methods => {}, # class name => instance methods
-# :attributes => {}, # class name => attributes
-# :modules => [], # classes and modules in this store
-# :ancestors => {}, # class name => ancestor names
-# }
