=head1 METHODS

=head2 new(\%data | $part)

construction or with just a part, which will result in an empty actions
hashref to be populated via add_action later

=head2 get_action($name)

Returns an action from this container based on the action name, or undef

=head2 add_action($action, [ $name ])

Adds an action, optionally providing a name to override $action->name

=head2 actions

Accessor to the actions hashref, containing all actions in this container.

=head2 part

stringifies to.
