Avoid "Segmentation Fault" on re-run

[jigyasa-grover]

On each run, a new file network_state.dat and a new folder output is created.

On re-running, this leads to a Segmentation Fault which can be done away with only after:

• Removing the above two as:

rm network_state.dat
rm -r output/

OR

• Renaming them

Hi, please feel free to change any documentation you want.
Here is where the topic is discussed already.

Was this occurring during tutorial runs?

@ludamad Yes. It actually shows up each time on re-run irrespectively.
