 * Define menu items and page callbacks.
 *
 * This hook enables modules to register paths in order to define how URL requests are handled. 
 * Paths may be registered for URL handling only, or they can register a link to be placed in a menu (usually the Navigation menu). 
 * A path and its associated information is commonly called a "menu router item" * This hook is rarely called (for example, when modules are enabled), and its results are cached in the database.
