 *
 * OVERRIDING THEME FUNCTIONS
 *
 * The Drupal theme system uses special theme functions to generate HTML output
 * automatically. Often we wish to customize this HTML output. To do this, we
 * have to override the theme function. You have to first find the theme
 * function that generates the output, and then "catch" it and modify it here.
 * The easiest way to do it is to copy the original function in its entirety and
 * paste it here, changing the prefix from theme_ to STARTERKIT_. For example:
 *
 *   original: theme_breadcrumb()
 *   theme override: STARTERKIT_breadcrumb()
 *
 * where STARTERKIT is the name of your sub-theme. For example, the zen_classic
 * theme would define a zen_classic_breadcrumb() function.
 *
 * If you would like to override any of the theme functions used in Zen core,
 * you should first look at how Zen core implements those functions:
 *   theme_breadcrumbs()      in zen/template.php
 *   theme_menu_item_link()   in zen/template-menus.php
 *   theme_menu_local_tasks() in zen/template-menus.php
