<bmx-stepper>
A task in steps - a wizard, a checkout, an onboarding - with a step list that shows where the reader is, what is done and what needs attention, and Back and Next buttons.
Next checks the fields in the step first: try it empty.
Finish completes the last step and fires bmxComplete.
Steps after the first wait until it is completed. The optional step can be passed over.
Down the side, any step in any order
