See https://grow.liferay.com/share/Allow+Buyers+to+Select+Their+Currency for details.
- This functionality will be encapsulated in a Liferay widget which admins or developers can drop on a page

- Don't use flags to represent currencies
- A user can select, at most, one currency at a given point in time
