Heroku API config (use ENV

quick_config.rb

# Use like this:
# QuickConfig.api(:spreedly, 'SPREEDLY_CORE_LOGIN', 'SPREEDLY_CORE_SECRET') do
#   SpreedlyCore.configure(ENV['SPREEDLY_CORE_LOGIN'],
#                          ENV['SPREEDLY_CORE_SECRET'],
#                          SPREEDLY_CORE[Rails.env]['token'])
# end
#
# or
#
# QuickConfig.api(:janrain, 'JANRAIN_API_KEY')
#
# Looks for a file in the project root, e.g. .spreedly, or .janrain in the
# above cases, and loads it to optionally set env vars for local development
#
# e.g.:
#   ENV['SPREEDLY_CORE_LOGIN']  = 'asdfasdf'
#   ENV['SPREEDLY_CORE_SECRET'] = 'fdsafdsa'
#
# Otherwise just defaults to using environment variables. Set your variables
# in your Heroku config to keep them out of your code.
