anchor.diff:  When prototyping against an in-memory database, it's useful to have a mechanism to create some initial state.
   This can be done using fixture scripts, accessible from the menu:Prototyping[Run Fixture Script]:
   
  -image::simpleapp/simpleapp/using/032-run-fixture-script-prompt.png[width="px",link="{imagesdir}/simpleapp/using/032-run-fixture-script-prompt.png"]
  +image::simpleapp/using/032-run-fixture-script-prompt.png[width="px",link="{imagesdir}/simpleapp/using/032-run-fixture-script-prompt.png"]
   
   This brings up a dialog to select the fixture script:
   
  -image::simpleapp/simpleapp/using/033-run-fixture-script-prompt.png[width="px",link="{imagesdir}/simpleapp/using/033-run-fixture-script-prompt.png"]
  +image::simpleapp/using/033-run-fixture-script-prompt.png[width="px",link="{imagesdir}/simpleapp/using/033-run-fixture-script-prompt.png"]
   
   This surfaces this code:
   
  
positive.code: 
  When executed, all objects created by the fixture are listed:
  
  image::simpleapp/simpleapp/using/034-run-fixture-script-result.png[width="px",link="{imagesdir}/simpleapp/using/034-run-fixture-script-result.png"]
  
  Navigating back to the home page shows the newly created objects:
  
  image::simpleapp/simpleapp/using/036-home-page-after-fixture-scriptpng.png[width="600px",link="{imagesdir}/simpleapp/using/036-home-page-after-fixture-scriptpng.png"]
  
  
  
  ==== Create an object
  
  You can also of course create new objects:
  
  image::simpleapp/simpleapp/using/040-create-object-from-menu.png[width="600px",link="{imagesdir}/simpleapp/using/040-create-object-from-menu.png"]
  
  To avoid obscuring the current page, this is configured to bring up a sidebar dialog:
  
  image::simpleapp/simpleapp/using/050-create-object-from-menu-prompt.png[width="600px",link="{imagesdir}/simpleapp/using/050-create-object-from-menu-prompt.png"]
  
  Hitting OK returns the created object:
  
  image::simpleapp/simpleapp/using/060-created-object.png[width="600px",link="{imagesdir}/simpleapp/using/060-created-object.png"]
  
  The above functionality is implemented by this code:
  
  
negative.code: 
  The `name` property is read-only, and can only be modified using the `updateName` action:
  
  image::simpleapp/using/070-update-name.png[width="600px",link="{imagesdir}/simpleapp/using/070-update-name.png"]
  
  The above functionality is implemented by this code:
