[Corelinux-public] AbstractFactory and Iterator models updated

[Frank V. C. <fr...@co...>]

Iterator needed a AssociativeIterator for use cases where the underlying
implementation has such.

Because this was useful (I wonder what drove what here) I incorporated
into AbstractFactory. In addition, AbstractFactory was type bound with
Identifier where it is up to the implementation to make that decision as
well as the management of the Allocators.

Code for AbstractFactory is being tested now, I am using the MazeFactory
example although it is fairly week.

I am planning to have 0.4.6 go out the door (wire) by Monday.
