Method; makes the last item in the current view of the collection the current item.

Example

The following code, attached to a Button component, goes to the last item in the DataSet collection:

my_ds.addItem({name:"item a", price:16});
my_ds.addItem({name:"item b", price:9});

my_ds.last();
while (my_ds.hasPrevious()) {
    my_ds.currentItem.price *= 0.5; // Everything's 50% off!
    my_ds.previous();
}

for (var i in my_ds.items) {
    trace(my_ds.items[i].name + ": " + my_ds.items[i].price);
}
