 Per default the wizard always starts with the first wizard step, after initialisation. The same applies for a reset, where the wizard normally resets to the first step.
 Sometimes this needs to be changed. If another default wizard step needs to be used, you can set it, by using the `[defaultStepIndex]` input of the wizard component.

 If you have an additional check or validation you need to perform to decide, if the step can be exited (both to the next step and to the previous step),
 you can either pass a boolean or a function, taking a `MovingDirection` enum and returning a boolean or a `Promise<boolean>`, to the `[canExit]` attribute of the wizard step.
 This boolean, or function, is taken into account, when an operation has been performed, which leads to a transition of the current step.
