Pops up a GUI dialog prompting the user to enter a password for the specified file.
<p>
The dialog is presented to the user when the iterator's hasNext() is called.
<p>
Repeated requests to the same iterator will adjust the dialog's title with a "try count" to
help the user understand the previous password was unsuccessful.
<p>
Iterator's hasNext() will return false if the user has previously canceled the dialog,
