The plugin take all of the data registered and created a multi-dimensional 
array in an option called ‘_shortcodes’. Existing shortcodes that WP is away of 
are also stored here with just their name and callback.
A few static methods for checking on shortcode info are provided. 
 GetShortcodeAtts($shortcode_name) 
 ShortcodeInPost($shortcode_name, $post_id)
Creating a new media button in the editor is easy with the <code>add_media_button()</code> 
method. Just pass your shortcode name, attributes, a page title, introductory 
text, and an icon image url.

WP Shortcodes API

Stores information about available shortcodes as an option and provides a method to easily add a media button with configurable options.
