	$tableBuilder = new tableBuilder;
	
	$tableBuilder->addField('name', 'string', FALSE);
	$tableBuilder->addField('description', 'description', FALSE);
	$tableBuilder->addField('date', 'TIMESTAMP', FALSE, tableBuilder::CURRENT_TIMESTAMP);
	$tableBuilder->addField('online', 'TINYINT(1)', FALSE);
