If you want to register custom view helpers with a module you can do so by using the service location built into the Skeleton Application and creating a module config that looks something like.
return array(
'view_helpers' => array(
'invokables' => array(
// generic view helpers
'truncate' => 'Zucchi\View\Helper\Truncate',
// form based view helpers
'bootstrapForm' => 'Zucchi\Form\View\Helper\BootstrapForm',
'bootstrapRow' => 'Zucchi\Form\View\Helper\BootstrapRow',
'bootstrapCollection' => 'Zucchi\Form\View\Helper\BootstrapCollection',
),
),
);
