Bug 331010 Track Model-Element contributors
We need to track which bundle contributed an model element to e.g. look up translations in the right package
bundles/org.eclipse.e4.ui.model.workbench/src/org/eclipse/e4/ui/model/application/util/ApplicationSwitch.java
/**
	 * The cached model package
	 * <!-- begin-user-doc -->
	 * <!-- end-user-doc -->
	 * @generated
	 */
	protected static ApplicationPackageImpl modelPackage;
	/**
	 * Creates an instance of the switch.
	 * <!-- begin-user-doc -->
	 * <!-- end-user-doc -->
	 * @generated
	 */
	public ApplicationSwitch() {
		if (modelPackage == null) {
			modelPackage = ApplicationPackageImpl.eINSTANCE;
		}
	}
	/**
	 * Calls <code>caseXXX</code> for each class of the model until one returns a non null result; it yields that result.
	 * <!-- begin-user-doc -->
	 * <!-- end-user-doc -->
	 * @return the first non-null result returned by a <code>caseXXX</code> call.
