    Finished up initial revision of GtkCellAreaBoxIter
    
    The interaction between this class and GtkCellAreaBox could
    use some optimization, maybe the cells and their sizes should
    be returned as a list and iterated over at the same time as
    requesting sizes instead of the hash table approach currently
    taken, however the code is clean this way for now.
