To run the project:
Download the repo.
In a command prompt, cd to the OUTER mysite directory.
Execute '$ python manage.py runserver'.
Finally, in your browser go to 'http://localhost:8000/inventory/'
I've added an expiry_date field to the requirement for an inventory item in the case where the items are perishable.
With this I added an option to view all items due to expire in the next 2 days or that have already expired.
Unfortunately, I ran out of time to allow blank entries for expiry in the case of non-perishables.
I also ran out of time to get the "Get all items from inventory for a given category" and "Get all items from inventory between a given price range" queries working.
