*** DATA UTILITY CLASSES ***

HISTORY: 

 2007-05-20 Wzl These classes have been designed to be db-engine agnostic, but I wasn't able

to test against anything other than MySQL nor was I able to implement the usage of the dbx_ functions, as the system that I was using didn't have them installed. 

 2007-08-30 Wzl posting this version at http://htyp.org/User:Woozle/data.php
 2007-12-24 Wzl Some changes seem to have been made as recently as 12/17, so posting updated version
 2008-02-06 Wzl Modified to use either mysqli or (standard) mysql library depending on flag; the latter isn't working yet
 2009-03-10 Wzl adding some static functions to gradually get rid of the need for object factories
 2009-03-18 Wzl debug constants now have defaults
 2009-03-26 Wzl clsDataSet.Query() no longer fetches first row; this will require some rewriting
   NextRow() now returns TRUE if data was fetched; use if (data->NextRow()) {..} to loop through data.
 2009-05-02 Wzl undocumented changes -- looks like:
   assert-checks return ID of an insertion
   function ExecUpdate($iSet,$iWhere)
   function SQLValue($iVal)
 2009-05-03 Wzl more undocumented changes -- looks like mainly $iWhere is now optional in GetData()
 2009-07-05 Wzl DataSet->__get now returns NULL if no field found; DataSet->HasField()
