/**
 * Report any content
 *
 * Related classes:
 * - BxDolReportQuery - report database queries
 * - BxBaseReport - report base representation
 * - BxTemplReport - custom template representation
 *
 * AJAX report for any content.
 *
 * To add report section to your feature you need to add a record to 'sys_objects_report' table:
 *
 * - id - autoincremented id for internal usage
 * - name - your unique module name, with vendor prefix, lowercase and spaces are underscored
 * - table_main - table name where summary reports are stored
 * - table_track - table name where each report is stored
 * - is_on - is this report object enabled
 * - base_url - base URL for reported object
 * - trigger_table - table to be updated upon each report
 * - trigger_field_id - trigger_table table field with unique record id, primary key
 * - trigger_field_author - trigger_table table field with author
 * - trigger_field_count - trigger_table table field with reports count
 * - class_name - your custom class name, if you overrride default class
 * - class_file - your custom class path
 *
 * You can refer to BoonEx modules for sample record in this table.
 *
 *
 *
 * @section example Example of usage:
 * You can show report in any place, using the following code:
 * @code
 * $o = BxDolReport::getObjectInstance('system object name', $iYourEntryId);
 * if (!$o->isEnabled()) 
 *     return '';
 * echo $o->getElementBlock();
 * @endcode
 *
 *
 * @section acl Memberships/ACL:
 * - report
 * - report view
 *
 *
 * @section alerts Alerts:
 * Alerts type/unit - every module has own type/unit, it equals to ObjectName.
 * The following alerts are rised:
 *
 * - type: 'object name', action: doReport
 * - type: report, action: do
