It just ends wpa_supplicant the nice way. If you kill the process directly, it 
leaves behind a lock file and won't start again until you remove it. Before I 
learned about wpa_cli I needed these two lines instead:

killall wpa_supplicant
rm -rf /var/run/wpa_supplicant

The post-down function needs to be there because otherwise the pre-up function 
will keep trying to run new instances of wpa_supplicant every time I bring 
the interface up.

Having those two functions instead of putting a single wpa_supplicant line in 
BootUp means when I do StopTask Network and StartTask Network, it is also 
stopping and restarting the wpa_supplicant. When I was experimenting with the 
supplicant settings I found this much more convenient than restarting it as a 
spearate step in betwen bringing the interface down and up.
