// checkstardone.C
// ===============
//
// check the availability of all star files for one dataset:
// if star has been executed successfully, this information has been inserted
// into the database (SequenceProcessStatus) with this macro this information
// is checked 
//
// executing the macro:
//  .x checkstardone.C+(1)
//
// The macro returns 0, if there's no connection to the database, 2 if
// star is not done, and 1 if star done, 3 in case of error.
// the return value is checked by the script, that executes the macro
//
// This macro is very similar to the macro checkfileavail.C
