Merge pull request #6 from BladeRunnerJS/getting-started

Getting started
Update the ExampleClass to the ExamplePresentationModel
Change the ExamplePresentationModel rather than the ExampleClass
test doesn't work with require yet

also, this should probably be an ExamplePresentationModelTest, but one of those isn't created automatically for us.
Use the correct ExamplePresentationModel code.
rename demo-event-hub to br.demo-event-hub
Update the Test to use the service
todoitems tests need to refer to br.demo-event-hub too.
Update the aspect examples to use the component interface stuff. Removed unnecessary service registry stuff.
Update getting_started.md
