* All views templates can be overridden with a variety of names, using
* the view, the display ID of the view, the display type of the view,
* or some combination thereof.
*
* 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
*
* - views-view-fields--foobar--page.tpl.php
* - views-view-fields--page.tpl.php
