#167 Dummy view for importing committees and countries via admin panel.

Adjusted the admin view to load csv files. Things still to do: write a unit test, and make it functional (it currently returns an index error because the csv reader returns an empty list).
This is incorrect.
- An HTTP response is what the server sends back to the client.
- An HTTP request is from the client to the browser.

The request is going to contain the CSV file that you need to read. Logically speaking, you just constructed that response... it's not going to have any data in it.
