Trello OAuth strategy for OmniAuth 1.0

This gem contains the Trello strategy for OmniAuth.

Trello uses the OAuth 1.0 flow, you can read about it here: https://trello.com/docs/gettingstarted/

gem install liangzan_omniauth-trello

use OmniAuth::Builder do
  provider :trello,
  ENV['TRELLO_KEY'],
  ENV['TRELLO_SECRET'],
  scope: 'read,write',
  app_name: 'YourApp',
  expiration: 'never'
end

If you don't set expiration, it defaults to 30days. The only other workable option is never.
