# We refer to times in the lifecycle of a record as "events". There are
# three events:
#
# - create
# - `after_create` we call `RecordTrail#record_create`
# - update
# - `after_update` we call `RecordTrail#record_update`
# - `after_touch` we call `RecordTrail#record_update`
# - `RecordTrail#save_with_version` calls `RecordTrail#record_update`
# - `RecordTrail#touch_with_version` (deprecated) calls `RecordTrail#record_update`
# - `RecordTrail#update_columns` is also referred to as an update, though
# it uses `RecordTrail#record_update_columns` rather than
# `RecordTrail#record_update`
# - destroy
# - `before_destroy` or `after_destroy` we call `RecordTrail#record_destroy`
#
# The value inserted into the `event` column of the versions table can also
# be overridden by the user, with `paper_trail_event`.
