[HiPerCoPS] Cell Interconnect

I really want to find a simple and clean way to connect the cells of a functional unit together. One option is to implement each cell with eight different pointers and connect the cells directly with these pointers. Connecting these pointers to an intermediate class is another possibility. This could help if I ever need to model delay, pipelining, or connection faults, but adds complexity to the overall system. Maybe the cells could account for delay, pipelining, and faults just as easily. I'll have to think about it more.
