[rufuspollock]

Create CountrySelector component and integrate with country performance graphs

Tasks

CountrySelector component.

• Uses select element - want autocomplete support etc
  • Consider using react-select - https://github.com/JedWatson/react-select
• List of countries - should be passed in
• Additional State: Uneditable or not. Selected value (included "" - i.e. empty)
• Test
  • Think about snapshot testing - https://facebook.github.io/jest/docs/snapshot-testing.html#snapshot-testing-with-jest

Country performance graph

• 5 selectors: (uneditable) for this country, (uneditable) for global, Three dropdowns for adding other countries. By dropdown = select with list of countries (preferably with auto-complete via chosen plugin or similar). also include null option so you can empty this.
• introduce redux store for graph dropdowns (which countries selected to show) and wire this into the main UI - i.e. changes in selectors should change graph
  • All above changes should operate via redux store state
• Test thoroughly - e.g. if i select a country then it is added to the graph (added state). If i set to null it is no longer in graph.
