_selection_state must return all possible step of

the wizard.

For each state but final, there must be a method named
|

"state_exit_X" where X is the name of the state. Each
|

|
|
of these method must set the next state in self.state.
|

For each state but start, there may be a method named
|
||
|
|
"state_previous_X" where X is the name of the state. Each
|
||
|
|
of these method must set the next state in self.state.
|

The final state has no related method because the view

should only display a button to close the wizard.

open_next, open_previous and _reopen_self should not need to be

overidden, but _selection_state and state_exit_start

likely will need to.
