We should be receiving an existing calculator in the form of an Excel spreadsheet w/ formulae. We can probably derive the calculations from/test against this. Will attach when we receive it.

We could include the brochure, details about eligible properties, background, etc.

Get the React front-end created with some minimal organization/structure

The current method used to provide user feedback is to mount a new geojson object over the original, with only the selected zone visible. This is pretty inefficient compared to modifying the original geojson's styles, however it will work as a stopgap for the moment. The docs mention a 'foreach' method that can add a listener to each feature in a geojson, which would let us modify the style on a specific feature directly on a click, however it doesn't exactly specify how to do this, and is pretty cryptic overall. Anyone feel free to take a crack at it!

If possible, we should also add a popup on the map stating which zone is selected. This shouldn't be very intrusive, and would give a big boost to usability.

Jud Knapp has a file of polygons representing the zones that can be loaded into QGIS mapping software (free/open-source).

Maybe we can try to overlay these on a Leaflet.js map for users to select their zone from (built on outputs of issue #8)

Precursor to #7, which actually involves displaying zones and allowing users to select one.
