I'm a huge fan of using properties and here seem to be lots of places
where parameterless functions should be properties that I can see. I
just thought that you had been in the habit of using functions in the
past and wanted to keep a consistency.

Good point, since I suggested we override the IterNChildren(TreeIter
iter) for the null case to accomodate gtk+ focused developers, using a
TreeIter.Zero value going to be intuitive for them? 

Coming from a gtk+ background you would most likely be looking to do
what the docs and tutorials say (supply a null value). So the question
is, which is a better replacement for a null treeiter, a function with
no parameters or one with TreeIter.Zero. On that instance I would say
stick with what we have now (an override that doesn't accept a TreeIter)
and do the same thing with it (call the RowCount Property).
