DiagnosticsViewModel Documentation

1. Purpose

DiagnosticsViewModel is a Prism-based ViewModel for the Diagnostics module within the TestSetups subsystem. It serves as the presentation logic layer for diagnostic UI, managing view binding, user notifications, and event-driven communication with other application components. The class is designed as a shared singleton (MEF CreationPolicy.Shared) and acts as a bridge between the IDiagnosticsTreeView and the application's event infrastructure.

    IEventAggregator eventAggregator,
    IUnityContainer unityContainer)

Initializes the ViewModel, sets the TreeView's DataContext to itself, creates interaction requests, and subscribes to RaiseNotification and BusyIndicatorChangeNotification events.
