The Problem

Create a calculator module that will be used to generate costs for a courier service. In particular, this calculator will calculate costs for a
driver and their van undertaking a delivery job.
Your module should factor in:

• The distance between the pickup location and the drop-off location(s)
• Anything between 1 and 5 drop-off locations
• A cost per mile that won't be the same for every job
• An optional cost for a second person to help the driver with the delivery job
• The need for a consistent quote data structure that can be shared with other calculators and passed to other modules
• Treat your calculator as one that will be built upon. Other developers will need to either extend on or build ones similar to the one you
  develop here. Be sure to structure your code in a way that accommodates this scenario, preferably using OOP methodology.

The resulting pricing data should include the following items:

• Number of drop-offs
• Total distance
• Cost per mile
• Extra person price
• Total price
• Any other data you might think is relevant

Example Scenario

• Cost per mile: £1.00
• No. of drop-off locations: 3
• Distances between locations:
  • 55 miles
  • b. 13 miles
  • c. 22 miles
  • Two-person job: no
    Additional Notes
• The "Extra Person" price is £15.
• The driver will only go to the pickup location once and load items for all drop-offs. They'll go from one drop-off to the next until all dropoffs are complete.
• Cost per mile and the "Extra Person" option will be consistent across all delivery services and their calculators.
• Expose your module’s functionality via an API, one or two endpoints as needed; a front-end is not required for this task and so you
  shouldn’t spend any time building one.

So what we're doing is making a microservice API module. This takes in data. Calculates the cost from distances and then outputs the price. So we would output total miles in example is 55+13+22 and total cost which in example is 1* (55+13+22)
Right looking at this What I need to do is.

• Create a Input Json Spec with what this calculator is going to take. (DA-1)
• create out put json spec with what this calculator is going to output. (DA-2)
• implement calculation logic (DA-5)
• All requests are POST (DA-4)
• Add client Secret logic to "secure" the API (DA-3)
• Save previous input calculation logic for debugging (More to flex we can use Laravels Elequant ORM and use migrations)(DA-6)
• Save Output json spec logic (DA-6)
• Make it multi user (DA-6)
