Detailed Description

Maintains a list of all servers and services available in the Dim nbetwork.

The idea of this class is to maintain a list of servers and services available in the Dim network. The servers are retrieved by subscribing to DIS_DNS/SERVER_LIST. The services are retrieved by subscribing to all servers SERVICE_LIST service.

The server names and the corresponidng DimInfo ovjects for their service lists are stored in fServerList.

The services of all servers are stored in the fServiceList.

From the services a lookup table fFormatList is created storing the received formats of all services/commands. The format list is only updated. So it might happen that formats for commands not available anymore are still in the list.

Whether commands or services are stored can be selected in the constructor by the type argument. Use "CMD" for commands and "" for services.

Todo:

• Resolve the dependancy on WindowLog, maybe we can issue the log-messages via MessageImp or we provide more general modfiers (loike in MLogManip)
• Maybe we also get updates (+/-) on the SERVCIE_LIST?
• check if we really need our own logging stream
• Implement fType=="*"
