Usage:
plot_tasks.py input.dat output.png [time-range-ms]
where input.dat is a thread info file for a step. Use the '-y interval'
flag of the swift MPI commands to create these. The output plot will be
called 'output.png'. Use the time-range-ms in millisecs to produce
plots with the same time span.
This file is part of SWIFT.
