 *

 * For each view, there will be a minimum of two templates used. The first

 * is used for all views: views-view.tpl.php.

 *

 * The second template is determined by the style selected for the view. Note

 * that certain aspects of the view can also change which style is used; for

 * example, arguments which provide a summary view might change the style to

 * one of the special summary styles.

 *

 * The default style for all views is views-view-unformatted.tpl.php

 *

 * Many styles will then farm out the actual display of each row to a row

 * style; the default row style is views-view-fields.tpl.php.

 *

 * Here is an example of all the templates that will be tried in the following

 * case:

 *

 * View, named foobar. Style: unformatted. Row style: Fields. Display: Page.

 *

 * - views-view--foobar--page.tpl.php

 * - views-view--page.tpl.php

 * - views-view--foobar.tpl.php

 * - views-view.tpl.php

 *

 * - views-view-unformatted--foobar--page.tpl.php

 * - views-view-unformatted--page.tpl.php

 * - views-view-unformatted--foobar.tpl.php

 * - views-view-unformatted.tpl.php
