/*

  Interface for importing address books using the standard UI.  Address
  book import occurs in several forms (yuck!).
  The destination can be 1..n new address books corresponding to the source
  format.  For instance a text file would import into a new address book
  with the same name as the text file, Eudora may import multiple address books
  with the same names as the ones in Eudora.
  The destination can be 1 pre-defined address book, all entries will be 
  added to the supplied address book - this allows the address book UI so provide
  an import command specific for an individual address book.
  
  The source can import 1 or mulitple address books.
  The address books can be auto-discoverable or user specified.
  The address books can require field mapping or not.
  
  All of this is rather complicated but it should work out OK.  
  1) The first UI
  panel will allow selection of the address book and will indicate to the user
  if the address book will be imported into an existing address book or new address
  books.  (This could be 2 seperate xul UI's?).
  2) The second panel will show field mapping if it is required - if it is required then
  there will be one panel per address book for formats that support multiple
  address books.  If it is not required then there will be no second panel.
  3) Show the progress dialog for the import - this could be per address book if
  mapping is required? what to do, what to doooooo.....
  4) All done, maybe a what was done panel??
