Short Day
Anne had an operation today, and so I half the day off to act as chauffeur and baby sitter.

In the couple of hours available for me to program I worked on the remove method on the ClosableIterators. I've finished the bulk of the coding on the ThreeFixedIterator, TwoFixedIterator and OneFixedIterator, though I haven't compiled or tested them yet. I still need to work on the GraphIterator, plus any cleaning which I've missed.

It shouldn't take me too long to finish it all tomorrow, and hopefully it won't take too long to test (and possibly debug).
