Hi David,

I made a useful step towards this today, by finishing off an earlier
idea for filtering which analysis objects are loaded by the yoda.read()
functions. The read functions now take optional strings, regex objects,
or iterables of them, as match & unmatch patterns. It passes a new test
that I added, which gives the idea:

$ cat tests/pytest-iofilter
#! /usr/bin/env python

import yoda

aos = yoda.read("test1.yoda", False, patterns=r".*_(eta|mass)_(2|4)")
print aos
assert len(aos) == 4

import re
aos = yoda.read("test1.yoda", False, patterns=[r".*_y_(1|3)",
re.compile(r".*_dphi_(2|4)")])
print aos
assert len(aos) == 3

I'm looking into using this with reinstated -m,-M options to
rivet-cmphistos now; hopefully it'll be as trivial as just passing the
command line options to the YODA function. I think this is the best way
to do it: put as much comparison & plot assembling logic as possible
into the libraries, and let the scripts be very thin UI wrappers on the
module functionality. Then we can reduce duplication, and it's also
useful to users who want to write a customised comparison script.
