Created a rough API by using REST framework

-We added some data into the admin page on the website and then dumped it all in apps/units/fixtures/initial_data.json.  This allows us to add this data back to our site using the migration tool.

-Next, we created the serializers.py.  This file is just like the models.py, but this will help display our database onto our API.

-Afterwards, we made the json_views.py.  This allows the API to display the data in our database.  We also created a filter to query out the id of each unit in our database.
EX: GET /api/v1/units?id=1 --will show the user the unit with id =1

-We also added the api_urls.py so that we can get the url to display our API to the users.

-We had an error in the original commit in the urls.py, so this time it is fixed.

-We also registered our admin site, updated our settings to include all of the Python packages, and added the admin url and api/v1 url to the gisc2/urls.py
