widget

Create instance of widget class. Class name is handled by the following rules:

- starting with the '+': use the entire name (except '+' sign)

- starting with the '~': use name (except '~' sign) prepended with application class name and '::Widget::'.

- other: use name prepended with application config parameter $config->{ widget }{ default_namespace } or string 'CatalystX::Widget::'

$c->widget('+Some::Class');  # Some::Class

$c->widget('~Class');        # App::Widget::Class

$c->widget('Class');         # CatalystX::Widget::Class

App->config{ widget }{ default_namespace } = 'Local';
$c->widget('Class');         # Local::Class
