Strings are passed to subprocess.Popen is used instead of sequences, so
proper quoting of parameters in command lines is needed to avoid
failures on filenames containing e.g. parenthesis. Use pipes.quote to
quote a string to avoid any issue with special characters.
Derived metrics may be calculated form data in raw output that is not
present in the resulting MeasurementCSV. This adds a method to provide
uniform access to raw artifacts generated by an instrument.
ARM energy probe sends SIGTERM to caiman, this signal can be missed by
caiman due caiman has not registered signal handler for SIGTERM. On the
other hand, caiman registers signal handler for SIGINT, this patch is to
change to use signal SIGINT to notify caiman.

This means when caiman is broken you can see the error message, instead of just
finding out later that there is no data.
We still don't detect caiman being broken until we call stop(), but it's still
an improvement.
Prior to this commit, measurements to be collected were specified via
"sites" and "kinds" parameters. This has the limitation that if you
wanted measurments of kind X from site A and kind Y from site B, you'd
have to specify them as
reset(sites=['A', 'B'], kinds=['X', 'Y'])
Which would have the effect of also collecting measurments Y for site A
and measurments X for site B. This commit adds the option of specifying
individual channels, via thier labels, e.g.
reset(channels=['A_X', 'B_Y'])
so that only the channels you're interested in will be collected.
