default value to return if the variable isn't set
Returns mixed
Example
// create a view and set some data
$view = new View;
$view->set(array('field1' => 'value1', 'field2' => 'value2');

// get a single value
$field1 = $view->get('field1');

// get a single value, set a default if the field does not exist
$field3 = $view->get('field3', 'value3');

$view->set('users', $users, false);

// or set an array

$view->set(array(
	'users' => $users,
	'articles' => $articles,
), null, true);

// If you need HTML / Javascript passed you need to set the last param to false
// when output encoding is enabled.

bind($key, $value = null)

Assigns a value by reference. The benefit of binding is that values can be altered without re-setting them. It is also possible to bind variables before they have values. Assigned values will be available as a variable within the view file.

Please note: these cannot be cleaned by output encoding and should thus be considered unsafe.
