[Trace] Feature request to pass 'normalize_time = False' into class Trace::__init__()

Created by: deggeman

To be able to sync the time (x axis) between kernelshark trace.dat and any TRAPpy based plot it would be nice to be able to see the same time on both of them. Lisa's Trace class should expose a parameter 'normalize_time' w/ a default value of True.
