[Halld-klf-beam] [EXTERNAL] followup G4 simulations of the KLF beamline

[Richard T. Jones]

Here are the slides that I shared today, with one adjustment. As requested,
I have updated the left column in the quad-plots for each detector
subsystem to correspond to the rate for the 10cm plug, instead of an
average over all plug thicknesses that many found difficult to interpret.
