#
# @example

# See `Object#inspect`. Returns some basic information about the
# object, including its class, object ID, and its most meaningful
# attribute. For a Feature model, this will be the name of the
# feature. If *verbose* is true, provides default Ruby inspection
# behavior instead.
#
# @example
# feature.inspect
# feature.inspect(verbose: true)
#
# @param verbose [Boolean] Whether or not to return the full details of
# the object. Defaults to false.
# @return [String] A string representation of this model
