Updated filename conventions and directory references to pull raw input from and write output to correct folders
Tested loop in chunk 3.  Renamed column variables to look for Correct_Grid_Position and Sample_Grid_Position (instead of sample image).  "totalskeep" data frame prints ok.  Did not test further output
Updated overall chi-squared test to accomodate 6 correctgrid and samplegrid possibilities.  Did not split by schedule
Modified individual chi-squared tests to look for choice and sample phase separately, but according to location and not image id as in group 2.
Updated trial type names in graph.  Seems to sum and print fine.  BUT: Why are match schedules showing different numbering for sample and choice?
