/**
 * Get content info from Content modules
 *
 * Add record to sys_objects_content_info table to provide unified access to module's content,
 * to get content info just create an instance of this class and request content info by id,
 * for example:
 * @code
 *  BxDolContentInfo::getObjectInstance('my_system')->getInfo(25); // 25 - is object id
 * @endcode
 *
 * Description of sys_objects_content_info table fields:
 * @code
 *  `name` - system name, it is better to use unique module prefix here, lowercase and all spaces are underscored
 *  `alert_unit` - unit name of the alert which will be fired 
 *  `alert_action_add` - action name of the alert which is fired after a content was added
 *  `alert_action_update` - action name of the alert which is fired after a content was updated
 *  `alert_action_delete` - action name of the alert which is fired after a content was deleted
 *  `class_name` - your custom class name, if you overrride default class
 *  `class_file` - your custom class path
 * @endcode
 *
