[fw-general] Concept of Zend Framework

[Joakim Gerth]

Hi all,

A really simple question for you guys.
In my effort to learn the framework I run into a lot of examples of the 
different components. For example, when reading about the 
zend_navigation I see the following,
-----------------

*Example 37.9. Creating a custom page type using the page factory*

To create a custom page type using the factory, use the option |type| to 
specify a class name to instantiate.

|
class My_Navigation_Page extends Zend_Navigation_Page
{
   protected $_fooBar = 'ok';

   public function setFooBar($fooBar)
   {
       $this->_fooBar = $fooBar;
   }
}

$page = Zend_Navigation_Page::factory(array(
   'type'    => 'My_Navigation_Page',
   'label'   => 'My custom page',
   'foo_bar' => 'foo bar'
));
|

----------------
How do I know where in the project structure this class/file should be 
created? All examples are like this and I don't in any case understand 
where to create things.

Regards,
Joakim
