/**
 * SECTION:hildon-set-password-dialog
 * @short_description: A dialog used to set, change or remove a password.
 * @see_also: #HildonGetPasswordDialog
 *
 * HildonSetPasswordDialog allows setting and changing a password. 
 * 
 * In Change mode: Dialog is used to change or remove an existing
 * password. Unselecting the check box dims the password fields below
 * it. If the dialog is accepted with 'OK' while the check box is
 * unselected, a Confirmation Note is shown.  If the Confirmation Note
 * Dialog is accepted with 'Remove', the password protection is removed.  
 * 
 * In Set mode: Set Password Dialog is used to define a password, or
 * change a password that cannot be removed.
