    // See Get Yahoo Mail OAuth2 Access Token for Desktop App 
    // for sample code showing how to obtain a Yahoo Mail access token.

    // In this example, our access token was previously saved to the following file which contains JSON like this:
    // {
    //   "access_token": "kCVQdnOdul...LHucA--",
    //   "refresh_token": "AIenVXETSo0jklFBVkPS8vVm8E.Ej9ToRG.xDbDYmZ65WIs5t6CZhDrD",
    //   "expires_in": 3600,
    //   "token_type": "bearer",
    //   "xoauth_yahoo_guid": "HGDQCVF5JB4YDOWHITQJFBHCWA"
    // }

    // Login
    // Use the email address of the GMail account that granted authorization.

    // that contains the collection of mailboxes.
    // It accepts two arguments: a refName and a wildcardedMailbox.

    var refName: String? = ""
    // refName is usually set to an empty string.
    // A non-empty reference name argument is the name of a mailbox or a level of
    // mailbox hierarchy, and indicates the context in which the mailbox
    // name is interpreted.

    // Select all mailboxes matching this pattern:
    var wildcardedMailbox: String? = "*"

    // Archive
    // Bulk Mail
    // Draft
    // Inbox
