#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).
The other classes in the file predated the convention we're going with, which is single quotes, no spaces around the text, and imperative verbs:

    '''Import a CSV file containing comittees.'''
