void __fastcall TMainForm::btLoadClick(TObject *Sender)
{
  /* Load the content of the input file in the first outline */
  Outline1->LoadFromFile("input.txt");
  /* Save the content of the outline in the memory stream */
  Outline1->SaveToStream(TempStream);
  /* Move the pointer at the begining of the stream */
  TempStream->Seek(0, soFromBeginning);
}
//---------------------------------------------------------------------------
void __fastcall TMainForm::btSaveClick(TObject *Sender)
{
  /* Load the content of the stream in the second outline */
  Outline2->LoadFromStream(TempStream);

  Outline2->SaveToFile("output.txt");
