  PackageName  [dddmp]

  Synopsis     [Low level functions to read in and write out bdds to file]

  Description  [A set of internal low-level routines of the dddmp package
    doing:
    <ul>
      <li> read and write of node codes in binary mode,
      <li> read and write of integers in binary mode,
      <li> marking/unmarking nodes as visited,
      <li> numbering nodes.
    </ul>
