# Mark an ActiveRecord model as having a state machine.
# The state of the model defaults to being stored on an attribute
# called `state` or can be specified via the `column` arg to
# the `stateful` call. To set the default state for a
# class, set a default column value for `state` in the database
# or use `initial: true` when defining the initial state.
#
# Use Symbols for all keys and values in state definitions.
