index.html and check.py don't agree on country format

[dleehr]

The comment in the index.html front matter prescribes a 2-letter lowercase country name:

country: "FIXME"      # country (lowercase two-letter ISO code such as "fr" - see https://en.wikipedia.org/wiki/ISO_3166-1)

But the check.py script expects the country to be a hyphenated full name:

COUNTRIES = [
    'Abkhazia', 'Afghanistan', 'Aland', 'Albania', 'Algeria',
    'American-Samoa', 'Andorra', 'Angola', 'Anguilla',
...
def check_country(country):
    '''"country" must be a hyphenated full country name from the list
    embedded in this script.'''

    return country in COUNTRIES

I'm happy to make the change but not sure which is preferred.

Ah, I see this is fixed in #36
