	ParentView	The control for this ViewModel.
	PauseResumeLogicalTaskTree	Command for the ContextMenuItem "Pause Tree" in the ContextMenu for the "MainGrid" of the control.
	ReloadLogicalTaskTree	Command for the ContextMenuItem "Reload" in the ContextMenu for the "MainGrid" of the control.
	Result	The ReturnObject of the assigned LogicalNode.
	RootLogicalTaskTreeViewModel	ViewModel of the superordinate LogicalTaskTree.
	ShowInfos	Command for the ContextMenuItem "Show info" in the ContextMenu for the "MainGrid" of the control.
	ShowLogLogicalTaskTree	Command for the ContextMenuItem "Show Log" in the ContextMenu for the "MainGrid" of the control.
	ShowSettingsLogicalTaskTree	Command for the ContextMenuItem "Show Settings" in the ContextMenu for the "MainGrid" of the control.

	ToolTipInfo	Returns the result of GetToolTipInfo(). This routine points to NextRunInfoAndResult by default, can be overwritten if necessary.
	UserDataContext	Binding to an optional, specific user view model.
	VisualTreeCacheBreaker	Unique GlobalUniqueIdentifier. Is assigned in the constructor and flows into the overwritten Equals method. This ensures that after reloading parts of the LogicalTaskTree and restarting Reload from previous states of the LogicalTaskTree Elements of the original LogicalTaskTree cached VisualTree instead of the newly loaded elements in the new VisualTree.
