Create a new class {{code language="none"}}StateUpdateFeature{{/code}} extending {{code language="none"}}AbstractUpdateFeature{{/code}} and register it by overriding {{code language="none"}}getUpdateFeature{{/code}} in the {{code language="none"}}TuringFeatureProvider{{/code}}. This new feature is responsible for updating the displayed text when the corresponding attribute in the domain model is changed outside the Graphiti editor. For example you could open the Turing Machine model with the //Sample Reflective Ecore Model Editor //in order to modify attributes. You can activate automatic updates of the diagram by extending {{code language="none"}}isAutoUpdateAtRuntime{{/code}} (resp. {{code language="none"}}Startup{{/code}} / {{code language="none"}}Reset{{/code}}) in the {{code language="none"}}TuringDiagramTypeProvider{{/code}} and returning {{code language="none"}}true{{/code}}. The update feature can be invoked explicitly in other features by calling the superclass method {{code language="none"}}updatePictogramElement{{/code}}.

Create a new class {{code language="none"}}StateLayoutFeature{{/code}} extending {{code language="none"}}AbstractLayoutFeature{{/code}} and register it by overriding {{code language="none"}}getLayoutFeature{{/code}} in the {{code language="none"}}TuringFeatureProvider{{/code}}. This new feature is responsible for updating the position and size of graphics algorithms of a state when the state is resized in the graphical editor or when the displayed text for the state name is updated. The layout feature can be invoked explicitly in other features by calling the superclass method {{code language="none"}}layoutPictogramElement{{/code}}.

	394	+Implement all created feature classes such that the editor behaves correctly when state names are modified or states are resized. You should aim for a good look-and-feel of your Turing Machine editor. If you like, you may also implement transition labels for displaying triggers and actions of transitions (not required for finishing the tutorial).
