 ### Configure backend
 Spec2 includes several backends (for the moment, Morphic and Gtk). A SpApplication configures a Morphic backend by default, but you can change it using `#useBackend:` or `#useBackend:with:` and sending the backend identifier and optionally a configuration (you may want to do specific backend things to configure your application behavior).

 While you can add your own way to access resources, SpApplication provides a property registration mechanism (a simple Dictionary and accessors), you may find useful to search at `accessing properties` protocol.
 ### Defining a start method.
 This is useful to give your application a starting window (in general, this is what you want).

 A configuration takes the responsibility to prepare an application to run properly. This preparation can be different depending on the platform where it is running, that's why you have several extension points you can extend/override:
