SL7 vs AL9

[jdkio]

Ideally, SL7 and AL9 should give us exactly the same results. We don't see major differences as we were worried about (see this conversation on slack), but we do see some minor differences. I think this can be attributed to differences in edep sim/geant4, which is used in finding the track length. But we also see minor differences in n hits per track. The setups are included in the next section, and the full set of comparison plots below that
