  CObject* RemoveHead();
 
  Remarks
 
  Removes the element from the head of the list and returns a pointer to
  it.
 
  You must ensure that the list is not empty before calling RemoveHead. If
  the list is empty, then the Debug version of the library asserts. Use
  ◄IsEmpty► to verify that the list contains elements.
 
  Return Value
 
  The CObject pointer previously at the head of the list.
 
  Example
 
  CObList list;
  CAge* pa1;
  CAge* pa2;
 
  list.AddHead( pa1 = new CAge( 21 ) );
  list.AddHead( pa2 = new CAge( 40 ) ); // List now contains (40, 21)
  ASSERT( *(CAge*) list.RemoveHead() == CAge( 40 ) );  // Old head
  ASSERT( *(CAge*) list.GetHead() == CAge( 21 ) );  // New head
  delete pa1;
  delete pa2;
