 When you're working on a multi step form wizard, you always define a *previous step* button and a *next step* button.
 When you add a button named `previous_step` or `next_step` to your form, this extension automatically adds an icon as follow:
 
-- ** previous_step **: `icon` is set to `glyphicon-step-backward` and `icon_position` is set to `before`
-- ** next_step **: `icon` is set to `glyphicon-step-forward` and `icon_position` is set to `after`

 So that, if you're satisfied of the default icons, you can simply write:
