Elixir Shipping Calculator

For the exercise you'll have to build a pricing model and then use it to calculate and display the prices of a number of shipments.

• Shipments are priced based on delivery range and weight.
• Range is determined by the zones of the origin and destination suburbs.
• If the suburbs are in the same zone, the range is same-zone.
• If the origin is in two different zones, the range is different-zone.
• If either the origin or destination is not in a zone, the shipment is not serviced.
• If the weight exceeds the maxium weight, the shipment is not serviced.

The pricing model should be built from the following two data files. These files can be found in the priv directory.

• zones.csv This contains the zone information. Zones are lists of suburbs, postcode pairs and a zone name.
• prices.csv Each row contains the price to deliver a parcel of a given weight for a given range. All prices are in the same currency and weights are in grams.
