/*
 * debug.php ::  Clase Debug, maneja reporte de eventos
 *
 * V4.0 copyright 2010-2011 by Gorlum for http://supernova.ws
 *  [!] Merged `errors` to `logs`
 *  [+] Now debugger can work with database detached. All messages would be dumped to page
 *  [+] Now `logs` has both human-readable and machine-readable fields
 *
 * V3.0 copyright 2010 by Gorlum for http://supernova.ws
 *  [+] Full rewrtie & optimize
 *  [*] Now there is fallback procedure if no link to db detected
 *
 * V2.0 copyright 2010 by Gorlum for http://supernova.ws
 *  [*] Now error also contains backtrace - to see exact way problem comes
 *  [*] New method 'warning' sends message to dedicated SQL-table for non-errors
 *
 * V1.0 Created by Perberos. All rights reversed (C) 2006
 *
 *  Experiment code!!!
 *
 * vamos a experimentar >:)
 * le veo futuro a las classes, ayudaria mucho a tener un codigo mas ordenado...
 * que esperabas!!! soy newbie!!! D':<
