Price checker

This test requires that you to implement a product price checker interface.

This widget should be a self-contained component that can placed within a larger admin page - you can simply place it within a basic index.html page.

We have provided you with this bare-bones Django project to get started. Simply fork this repo and begin working, ensuring that you install and add to the requirements contained in requirements.txt.

The project contains:

1. The basic infrastructure to start running, with an sqlite DB
2. A products app containing two models - Product and PricingBlock
3. An initial data fixture to get going
4. A price search routine in products.utils.get_price
5. A simple unit test for get_price

The tasks you must carry out are as follows:

1. Optimise the products.utils.get_price function which is very long running under certain circumstances and contains faults
2. Implement the form as specified in the wireframe above using a modern javascript framework such as React, Vue or Angular
3. Please ensure the form is presentable - you may use a CSS framework like bootstrap or material-ui or roll your own
4. Hook up the interface to the backend, such that the user can find the cheapest price by specifying a product, start date and nights

Please provide us with information on how to run the code you provide.
