/**
 * Elgg's view system.
 *
 * The view system is the primary templating engine in Elgg and renders
 * all output.  Views are short, parameterised PHP scripts for displaying
 * output that can be regsitered, overridden, or extended.  The view type
 * determines the output format and location of the files that renders the view.
 *
 * Elgg uses a two step process to render full output: first
 * content-specific elements are rendered, then the resulting
 * content is inserted into a layout and displayed.  This makes it
 * easy to maintain a consistent look on all pages.
 *
 * A view corresponds to a single file on the filesystem and the views
 * name is its directory structure.  A file in
 * <code>mod/plugins/views/default/myplugin/example.php</code>
 * is called by saying (with the default viewtype):
 * <code>echo elgg_view('myplugin/example');</code>
 *
 * View names that are registered later override those that are
 * registered earlier.  For plugins this corresponds directly
 * to their load order: views in plugins lower in the list override
 * those higher in the list.
 *
 * Plugin views belong in the views/ directory under an appropriate
 * viewtype.  Views are automatically registered.
 *
 * Views can be embedded-you can call a view from within a view.
 * Views can also be prepended or extended by any other view.
 *
 * Any view can extend any other view if registered with
 * {@link elgg_extend_view()}.
 *
 * Viewtypes are set by passing $_REQUEST['view'].  The viewtype
 * 'default' is a standard HTML view.  Types can be defined on the fly
 * and you can get the current viewtype with {@link elgg_get_viewtype()}.
 *
 * @note Internal: Plugin views are autoregistered before their init functions
 * are called, so the init order doesn't affect views.
 *
 * @note Internal: The file that determines the output of the view is the last
 * registered by {@link elgg_set_view_location()}.
