* RELEASED LICENSE: BSD style (use it, u don't have to make YOUR source public)

* with your name on it ...
* SHORT DESCRIPTION:
* DB Array IO Class:
* writes, reads or deletes a complete array (one data set) in/out a
* table from the connected DB.
* you don't have to write any SQL queries, worry over update/insert
*
* PUBLIC VARIABLES

* PRIVATE VARIABLES

* PUBLIC METHODS
*
* PRIVATE METHODS
*
* HISTORY:
* 2005/07/07 (cs) updated array class for postgres: set 0 & NULL if int field given, insert uses () values () syntax
* 2005/03/31 (cs) fixed the class call with all debug vars
* 2003-03-10: error_ids where still wrong chagned 11->21 and 12->22
* 2003-02-26: db_array_io is no longer single class but extens db_io,
* as it needs it anyway
* moved the class info vars into class_info array into
* the constructor, removed info function
* 2003-02-24: in db_delete moved query build to top, or pk_name/value
* will be reset before delete is done
* 2002-12-20: just added info() method
* 2002-12-17: splitted the class from other file (with main db wrapper)
