 * All other action hooks and filters described before each function where applicable

 * Important: dashboard_save_settings() function should be registered as wp_ajax action in the plugin which uses this class to avoid conflicts.
 * 	Action name should be following - 'wp_ajax_<plugin_class_name>_save_settings'
