AE: Change to use the ellipse parameters of the final focus x-y histogram (No. 18) for part of the TURTLE input
AE: Copy a 2D histogram of the muPC beam distribution to the TURTLE_fits file
AE: Put the direction and position modes into one if-block since the new calculation won't be able to split them
AE: Add a comment describing my current plan for using the data as an input
AE: Have the first two steps completed for the new input beam distribution
AE: Add a couple of histograms of the random positions we draw from the muPC and FF distributions
AE: Add z values to the muPC and FF positions and use G4ThreeVectors
AE: Some indentation of the turtle mode
AE: Make the trigger box slightly shorter so that the final focus is actually outside it
AE: Add the final part of the TURTLE position/direction mode
