onboarding wizard design for simplicity and flexbility

	/**
	* Simple wizard
	* design philosophy: simplicity, wysiwyg, isolated responsibilities
	* key design decision: each wizard step is aware that it's part of a wizard
	* upside: simple and flexible
	* downside: more boilerplate
	* case-by-case: when we need to add or rearrange the steps, we also need to modify existing steps (smell: Shotgun Surgery)
	* however, this is aligned with the key design decision
	*
	* alternative key design: opposite - isolated steps that are unaware of the fact that they're part of a wizard

Compare different organization

	/*
	Background:
	We have a component with two buttons, one button for adding a new empty fee variation, another for duplicating an existing fee variation.

	for example:

	button(click='uiModel.addVariation()') Add New
	button(click='uiModel.duplicateVariation(seed)') Duplicate

	There are four different implementations:
