I have the following output from trying to run_simulation.py

`Traceback (most recent call last):
File "run_simulation.py", line 47, in
run_simulation(0.8, 0, 5, 50)
File "run_simulation.py", line 44, in run_simulation
print("Final RTT is %.2f") % observer.measure_rtt()
TypeError: unsupported operand type(s) for %: 'NoneType' and 'int'

Compilation exited abnormally with code 1 at Tue Nov 5 10:05:50`

I can fix it my changing the print-statement to

print("Final RTT is", observer.measure_rtt())

but I'm guessing this is not a problem which is consistent over our python interfaces. Not sure what produces this error.

• Add venv env instructions
• Take in P=<double between 0 and 1> and Q=<double between 0 and 1> as command line args with default values
• Add help option

considering the potential of using RRM to have more than one bit assisting in latency measurement as per previous proposals

Sometimes I can see the wrong index (not the 0th one) being changed in the path if P or Q > 0

I have the below out from run_simulation(0.2, 0, 5, 50):

Here in tick 6, the bit starts spinning at v=1 as I would expect:

Tick:
6
Client ->
[1, 0, 0, 0, 0]
-> Server
Client <-
[0, 0, 0, 0, 0]
<- Server

In tick 7, another v=1 bit is added in the beginning of the client->server path:

Tick:
7
Client ->
[1, 1, 0, 0, 0]
-> Server
Client <-
[0, 0, 0, 0, 0]
<- Server

Here at tick 8 it's not obvious to me what's happening. The system remains in the same state as in tick 7, so 0.2 is doing something - but what?

Tick:
8
Client ->
[1, 1, 0, 0, 0]
-> Server
Client <-
[0, 0, 0, 0, 0]
<- Server

Here at tick 9 it looks as if the P=0.2 is making the middle of the path randomized somehow. I would expect to be seeing [1, 0, 1, 1, 0] in the C->S row, and to have seen [0, 1, 1, 0, 0] in tick 8.

Tick:
9
Client ->
[1, 1, 0, 1, 0]
-> Server
Client <-
[0, 0, 0, 0, 0]
<- Server

Here follow three repetitions of tick 9:

Tick:
10
Client ->
[1, 1, 0, 1, 0]
-> Server
Client <-
[0, 0, 0, 0, 0]
<- Server

Tick:
11
Client ->
[1, 1, 0, 1, 0]
-> Server
Client <-
[0, 0, 0, 0, 0]
<- Server

Tick:
12
Client ->
[1, 1, 0, 1, 0]
-> Server
Client <-
[0, 0, 0, 0, 0]
<- Server
