/*************************************************************
*
*
* PURPOSE:
* test rasj: simple open/read query/close cycle.
* rasj test program for executing a query against some rasdaman database.
* Note: database is opened readonly, so send only SELECT queries.
*
* @param --server s - use server s (default: localhost)
* @param --port p - use server port p (default: 7001)
* @param --database d - use database d (default: RASBASE)
* @param --user u - log in as user u (default: rasguest)
* @param --passwd p - log in with password p (default: rasguest)
* @param --query q - send SELECT query string q to server (default: "select r from RAS_COLLECTIONNAMES as r"")
* @param --count c - execute query c times (default: 1)
*
*
* COMMENTS:
* - no parameter line error handling
