# purpose:
#        generate data reduction graphs for the multi-threaded list project
#
# input: lab2_list.csv
#       1. test name
#       2. # threads
#       3. # iterations per thread
#       4. # lists
#       5. # operations performed (threads x iterations x (ins + lookup + delete))
#       6. run time (ns)
#       7. run time per operation (ns)
#
# output:
#       lab2_list-1.png ... cost per operation vs threads and iterations
#       lab2_list-2.png ... threads and iterations that run (un-protected) w/o failure
#       lab2_list-3.png ... threads and iterations that run (protected) w/o failure
#       lab2_list-4.png ... cost per operation vs number of threads
#
# Note:
#       Managing data is simplified by keeping all of the results in a single
#       file.  But this means that the individual graphing commands have to
#       grep to select only the data they want.
