 * Adds contextual action hooks to the theme.  This allows users to easily add context-based content 
 * without having to know how to use WordPress conditional tags.  The theme handles the logic.
 *
 * An example of a basic hook would be 'woo_head'.  The woo_do_atomic() function extends that to 
 * give extra hooks such as 'woo_head_home', 'woo_head_singular', and 'woo_head_singular-page'.
 *
 * Major props to Ptah Dunbar for the do_atomic() function.

 * @since 3.9.0
 * @uses woo_get_query_context() Gets the context of the current page.
