# Preloads ActiveRecord model associations with shared object references.
# This internally uses ActiveRecord::Associations::Preloader but works around some of its limitations.
# It works around a bug with associations containing loaded/unloaded models. https://github.com/rails/rails/issues/32140
#
# Usage:
#   Preloader.new(models, association_spec).preload
# Also supports a third `scope` argument that is used when querying.
#
# There is an additional class utility method `uniquify_associations` to share object references that can be useful in preloading.
