// pqServerManagerSelectionModel. When the selection in the pqDataInformationModel
// changes, the pqServerManagerSelectionModel will be updated and vice versa.
// Selection adaptors are part of the "Synchronized selection" mechanism
// making it possible to different views connected to different models 
// which are based on pqServerManagerModel to coordinate the selection state.
