 * and existing user and view the data for a user.
 *
 * It should be possible to edit a single user account at a time or multiple
 * accounts. When multiple accounts are edited, the UserPanel which serves as
 * the editor is not loaded with data for any particular user. When the data is
 * read back from this dialog, only the data which has changed is saved for all
 * users while all other data remians unchanged. This allows for bulk
 * provisioning of users.
 *
 * In order to edit a user, a UserPanel is instantiated, the pServer is
 * queried for the user's data, then the UserPanel is instructed to load the
 * data into all its elements for display. The UserPanel is then dispalyed in
 * a modal dialog. When the dialog has been dismissed the data is collected from
 * the UserPanel and saved to the table model and the pServer.
