** We have done kinetic firewall in exercise VII and imitated the same firewall using pox in exercise VIII. Now, we will imitate the same firewall using pyretic.
** The basic solution is taken from the Internet [https://dl.dropboxusercontent.com/u/1652374/SDN_Course/Exercises/pyretic_gardenwall_internetsolution1.py], test if it is able to block h1 when "infected". Note that we will only use the "infected == True" for this exercise.
