A Fresher Cache adds an admin bar menu that gives easy access to functions that refresh (i.e, regenerate or invalidate) 
cached items. Out of the box, the plugin provides easy access to refresh items that WordPress Core caches; however, the true 
power of the plugin is its API that allows developers to easily add items to the menu that initiate custom functions that 
refresh cached items.
For instance, imagine that you wrote a function called “my_update_all_term_caches” that loops through all of the terms 
in your WordPress install and updates the cache for each item. You can add this function to the “Freshen” admin bar 
menu with the following API call:
<pre><code>function my_update_all_term_caches_menu_item() {
 $args = array(
 'id' => 'my-update-all-term-caches',
 'title' => 'Update Term Cache',
 'function' => 'my_update_all_term_caches'
 );

 afc_add_item( $args );
}
add_action( 'init', 'my_update_all_term_caches_menu_item' );
</code></pre>
This code will generate a menu item labelled “Update Term Cache” that creates a link that will run the function defined 
in the “function” key of the $args array (in this case, my_update_all_term_caches()).
The primary purpose of this plugin is to provide an easy tool for developers to refresh cached items when developing new 
features. Additionally, it can serve as a convenient tool for users to be able to update cached items when needed.
Note that this is not merely a wrapper for the admin bar API. Rather, it allows you to add items to the admin bar and provides 
all of the necessary coding that will link a callback function to a menu item. You can think of it as an extension of 
the admin bar that adds a very specific functionality. The plugin also uses the admin bar as intended and only adds a 
few extra arguments that support the functionality of this plugin.
