**breaking** mini-ndn: re-design

refs: #5062

Everything is now done through examples like Mininet.
bin/minindn no longer provided as a binary installed in the system
bin/minindnedit GUI: will no longer be maintained
Remove cluster edition, will be re-introduced later

+Connect Mini-NDN nodes to an outside network
+---------------------------------------------
+
+Mini-NDN nodes can be connected to an outside network indirectly by
+running NFD on the local machine:
+
+::
+
+    (Mini-NDN node) ------ (NFD running on the host machine where Mini-NDN is running) ------- (External Network)
+
+Add a node in root namespace
+____________________________
+
+For this simple example, we can use a single node topology with node 'a'
+
+If we want node 'a' to connect to the host machine, we need to add a
+"root" node which has a link with node "a."
+
+Then the following code can be used:
+
+.. code:: python
+
+    topo = Topo()
+    root = topo.addHost('root', inNamespace=False)
+    a = topo.addHost('a')
+    topo.addLink(root, a, delay='10ms')
+
+    ndn = Minindn(topo=topo)
+
+    ...
+
+Configuration
+_____________
+
+Run Mini-NDN with the above code and issue ifconfig on the local
+machine to confirm the addition of the interface. You should be able to
+locate "root-eth0":
+
+::
+
+    root-eth0 Link encap:Ethernet  HWaddr 3e:eb:77:d2:6f:1f
+              inet addr:1.0.0.9  Bcast:1.0.0.11  Mask:255.255.255.252
+              inet6 addr: fe80::3ceb:77ff:fed2:6f1f/64 Scope:Link
+              UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
+              RX packets:34 errors:0 dropped:0 overruns:0 frame:0
+              TX packets:33 errors:0 dropped:0 overruns:0 carrier:0
+              collisions:0 txqueuelen:1000
+              RX bytes:2667 (2.6 KB)  TX bytes:2797 (2.7 KB)
+
+To make the IP address associated with this interface persistent, add
+the following line to /etc/network/interfaces and reboot your machine:
+
+::
+
+    iface root-eth0 inet manual
+
+Check connection
+________________
+
+After rebooting, run Mini-NDN and issue the following command:
+
+::
+
+    mini-ndn>net
+    a a-eth0:b-eth0 a-eth1:c-eth0 a-eth2:root-eth0
+
+Node "a" is connected to "root-eth0". Now issue "ifconfig a-eth2" on
+node "a":
+
+::
+
+    mini-ndn>a ifconfig a-eth2
+    a-eth2    Link encap:Ethernet  HWaddr fa:76:d4:86:d3:ba
+              inet addr:1.0.0.10  Bcast:1.0.0.11  Mask:255.255.255.252
+
+As learned from the previous step, the IP address of root-eth0 is
+1.0.0.9.
+
+::
+
+    mini-ndn>a ping 1.0.0.9
+    PING 1.0.0.9 (1.0.0.9) 56(84) bytes of data.
+    64 bytes from 1.0.0.9: icmp_seq=1 ttl=64 time=0.137 ms
+    64 bytes from 1.0.0.9: icmp_seq=2 ttl=64 time=0.123 ms
+
+The host machine will also be able to ping node "a":
+
+::
+
+    VirtualBox:~$ ping 1.0.0.10
+    PING 1.0.0.10 (1.0.0.10) 56(84) bytes of data.
+    64 bytes from 1.0.0.10: icmp_seq=1 ttl=64 time=0.086 ms
+
+Run NFD on local machine and register route
+___________________________________________
+
+Start NFD on the local machine by using:
+
+::
+
+    sudo nfd
+
+The "nfd-start" script cannot be used, since the script allows only one
+instance of NFD at a time. The NFD processes running on the Mini-NDN
+nodes will prevent the "nfd-start" script from working.
+
+Now, using "nfdc register", we can register a route from node "a" in
+Mini-NDN to the NFD process on the host machine and from the host
+machine to an external machine.
+
+Also, if the local machine has a public IP, Mini-NDN nodes can be
+reached via external machines.
