  uilogin - Retrieves the token from a ui dialog

    Note: When the token is retrieved for the first time, it is stored in
    an environment variable. This function will try to first retrieve the
    token from the environment variable, and if the variable does not
    exist, the ui dialog is opened for user to enter username and password.

    Also, if the token exists, but has expired, the dialog will open for
    user to re-enter username and password.
