# The columns you want:
#
#       c1 = 2 * NUMBER_OF_WHATS * FILE_INDEX + 2 * WHAT_INDEX + 1
#       c2 = 2 * NUMBER_OF_WHATS * FILE_INDEX + 2 * WHAT_INDEX + 2
#       tit = 'WHAT FILE histogram'
#
# Where WHAT_INDEX is:
#       0 -- time
#       1 -- iterations
#       2 -- cost
#       3 -- cusps-in-path
#       4 -- connecteds-in-path
#       5 -- nodes
#
# FILE_INDEX starts at 0, files are ordered alphabetically.
