Fetch Gists from the API

# GETs the URI and returns a Ruby hash.

result = fetch_uri(uri)
JSON.load(result.body)
end
# Gets the next uri via pagination in headers

result = fetch_uri(uri)

# stupid parsing. We'd use something real here in
# production

string =~ /\<(.*)\>; rel="(.*)"/
[$2, $1]
end

# omg hax! I don't want to deal with templates, so
# let's punt on that. You'd use a real URI templates
# parser in real code.

# Let's begin!
