	//TO INSTALL: Put this script in an appropriate file, and then
	// refer to it in a manner somewhat like the following code:
		//include our snippet
		require ('tableview.php'); //Or whatever you name the snippet
		//Override some defaults
		$tblQuery['columns']='*';						//The columns to select
		$tblQuery['tblName']='HachiSoft';				//The table to select from
		$tblQuery['where']="WebDesign='Excruciating'";	//The Where clause for the SELECT
		$tblQuery['viewSize']=10;						//How many records to a page
		//Pass along any self-referral parameters for table ordering and paging
		if (isset($orderBy))

			$tblQuery['viewStart']=$viewStart;  //The starting offset for record paging
		if (isset($orderDir))

		//To Set a default self-referral parameter:
		//if (isset($orderDir))
		//	$tblQuery['orderDir']=$orderDir;
		//	$tblQuery['orderDir']='DESC';
		//To set column-specific formatting and processing:
