changes in restart behaviour: - restart mechanism is now called from init(..) method in time manager for all models via problem().restart(...); - hence, calls to problem or models in application files and in the default start procedure are deleted (included in timeManager) - timeManager().init(...) now has a real restart bool defining if a restart was called by the user. Bool is true if restart is desired. - Decoupled models: to enable restart, the writer is only called with the access function to avoid segmentation fault. - Adapt tutorial to the change
