NameError (uninitialized constant ChatWork::AuthenticateError)
irb(main):002:0> ChatWork::APIError
=> ChatWork::APIError
irb(main):003:0> ChatWork::AuthenticateError
=> ChatWork::AuthenticateError
Why ?

autoload is missing here. https://github.com/asonas/chatwork-ruby/blob/v0.6.1/lib/chatwork.rb#L6-L8
asonas / chatwork-ruby

uninitialized constant ChatWork::AuthenticateError #44

Why ?
