/**
* Execute functions hooked on a specific action hook.
*
* This function invokes all functions attached to action hook $tag. It is
* possible to create new action hooks by simply calling this function,
* specifying the name of the new hook using the <tt>$tag</tt> parameter.
*
* You can pass extra arguments to the hooks, much like you can with
* applyFilters().
*
* @see applyFilters() This function works similar with the exception that
* nothing is returned and only the functions or methods are called.
*
* @param string $tag The name of the action to be executed.
* @param mixed $arg,... Optional additional arguments which are passed on to the functions hooked to the action.
*
* @return null Will return null if $tag does not exist in $wp_filter array
