Merge branch 'threadpool_task_plots' of gitlab.cosma.dur.ac.uk:swift/swiftsim into threadpool_task_plots

examples/plot_threadpool.py

+#!/usr/bin/env python
+"""
+Usage:
+    plot_threadpool.py [options] input.dat output.png
+
+where input.dat is a threadpool info file for a step.  Use the '-Y interval'
+flag of the swift command to create these. The output plot will be called
+'output.png'. The --limit option can be used to produce plots with the same
+time span and the --expand option to expand each thread line into '*expand'
+lines, so that adjacent tasks of the same type can be distinguished. Other
+options can be seen using the --help flag.
