[asdf-devel] Pushed version 3.1.0.52 -- first version with checks for OPERATION subclasses -- please test!

[Robert P. Goldman]

P.S.  I made a mistake and missed the regression test that accompanies
the modifications in 3.1.0.52, so that is now available as 3.1.0.53.  D'oh.

This won't change how you test *your* systems, but if you want to run
make test or run-tests.sh, please pull another update.

thanks!
