/**
 * @defgroup themeable Default theme implementations
 * @{
 * Functions and templates for the user interface to be implemented by themes.
 *
 * Drupal's presentation layer is a pluggable system known as the theme
 * layer. Each theme can take control over most of Drupal's output, and
 * has complete control over the CSS.
 *
 * Inside Drupal, the theme layer is utilized by the use of the theme()
 * function, which is passed the name of a component (the theme hook)
 * and an array of variables. For example,
 * theme('table', array('header' => $header, 'rows' => $rows));
 * Additionally, the theme() function can take an array of theme
 * hooks, which can be used to provide 'fallback' implementations to
 * allow for more specific control of output. For example, the function:
 * theme(array('table__foo', 'table'), $variables) would look to see if
 * 'table__foo' is registered anywhere; if it is not, it would 'fall back'
 * to the generic 'table' implementation. This can be used to attach specific
 * theme functions to named objects, allowing the themer more control over
 * specific types of output.
 *
 * As of Drupal 6, every theme hook is required to be registered by the
 * module that owns it, so that Drupal can tell what to do with it and
 * to make it simple for themes to identify and override the behavior
 * for these calls.
 *
 * The theme hooks are registered via hook_theme(), which returns an
 * array of arrays with information about the hook. It describes the
 * arguments the function or template will need, and provides
 * defaults for the template in case they are not filled in. If the default
 * implementation is a function, by convention it is named theme_HOOK().
 *
 * Each module should provide a default implementation for theme_hooks that
 * it registers. This implementation may be either a function or a template;
 * if it is a function it must be specified via hook_theme(). By convention,
 * default implementations of theme hooks are named theme_HOOK. Default
 * template implementations are stored in the module directory.
 *
 * Drupal's default template renderer is a simple PHP parsing engine that
 * includes the template and stores the output. Drupal's theme engines
 * can provide alternate template engines, such as XTemplate, Smarty and
 * PHPTal. The most common template engine is PHPTemplate (included with
 * Drupal and implemented in phptemplate.engine, which uses Drupal's default
 * template renderer.
 *
 * In order to create theme-specific implementations of these hooks, themes can
 * implement their own version of theme hooks, either as functions or templates.
 * These implementations will be used instead of the default implementation. If
 * using a pure .theme without an engine, the .theme is required to implement
 * its own version of hook_theme() to tell Drupal what it is implementing;
 * themes utilizing an engine will have their well-named theming functions
 * automatically registered for them. While this can vary based upon the theme
 * engine, the standard set by phptemplate is that theme functions should be
 * named THEMENAME_HOOK. For example, for Drupal's default theme (Bartik) to
 * implement the 'table' hook, the phptemplate.engine would find
 * bartik_table().
 *
 * The theme system is described and defined in theme.inc.
 *
 * @see theme()
 * @see hook_theme()
 * @see hooks
 * @see callbacks

 * Note that the base theme's form alterations will be run before any sub-theme
