Hints for Assignment 2

When passing around the path lists via replicate, you may get all of the nodes pointing to the same copy of data. This is due to the way the replicate function is currently written. If it is just a number (like hops), then it copies over the value correctly, but for more complex objects like lists, it returns a pointer instead, and all of them get set to the SAME pointer. So the best workaround is to create a new list, and loop over the values in self.path, append them to the new list, append the last value (self.host.id) to the new list, and put THAT list into the dictionary that is passed into the replicate function.

To run two programs on separate nodes, just type the desired program name in twice in the commmand line.
