# Usage: prot_discretizer.py
#
# Read test protocols and round run times upwards towards
# discrete values selectable  via command line switches:
#
# --constant: Set all times to 0.
# --equidist[=<val>]: Round all values to the nearest integral
#   multiple of <val>. If <val> is omitted, assumes 10.
# --prop: Round all times to 1,2,5,10,20,50,100,...
