	 * $queryid can be either the id of a query from the dbqueries table, or the
	 * name of a table.
	 *
	 * if it is the name of a table , $params MUST include self::TYPE_KEY of either update, insert, select, or delete.
	 *
	 * $params includes a list of parameters. Here's how it gets interpreted.
	 *
	 * If the queryid was the name of a table and type was "update", one of the params
	 * must be the primary key of the table. All the other parameters will be matched against
	 * the table field names, and appropriate fields will be updated. The return value will
	 * be false if an error is generated and true otherwise
	 *
	 * If the queryid was the name of a table and type was "delete", one of the params
	 * must be the primary key of the table. All the other parameters will be ignored
	 * The return value will be false if an error is generated and true otherwise
	 *
	 * If the queryid was the name of a table and type was "insert", all the parameters will be
	 * matched against the table field names, and appropriate fields will be set in the insert.
	 * The return value is the primary key of the inserted record.
	 *
	 * If the queryid was the name of a table and type was "select", all the parameters will be
	 * matched against the table field names, and appropriate fields will be part of the
	 * "where" clause of the select. The return value will be a vB_dB_Result object
	 * The return value is the primary key of the inserted record.
	 *
	 * If the queryid is the key of a record in the dbqueries table then each params
	 * value will be matched to the query. If there are missing parameters we will return false.
	 * If the query generates an error we return false, and otherwise we return either true,
	 * or an inserted id, or a recordset.
