# Utility class for dealing with Include Directives

class << self
# Let's say the user requested these sideloads:
#
# GET /posts?include=comments.author
#
# But our resource had this code:
#
# sideload_whitelist({ index: [:comments] })
#
# We should drop the 'author' sideload from the request.
#
# Hashes become 'include directive hashes' within the library. ie
#
# [:tags, { comments: :author }]
#
# Becomes
#
# { tags: {}, comments: { author: {} } }
#
# @param [Hash] requested_includes the nested hash the user requested
# @param [Hash] allowed_includes the nested hash configured via DSL
# @return [Hash] the scrubbed hash
