// a service to create CoraCoolDatabase objects given a SEAL context (where
// CORAL libraries are already loaded) the corresponding COOL IDatabaseSvc 
// (plays an analogous role to COOL IDatabaseSvc)
// This can be created directly, or via CoraCoolDatabaseSvcFactory singleton
// which sets up CoraCool and COOL standalone in one call
