a whole lot of refactor...
fix ukidss defaults
major refactor removing class_or_instance complete?
(Simbad still has "property class or instance" which is probably not
needed)
fixed more broken tests.  They all pass for py2.6, but nothing works at
all for py2.7 because something is really broken in my personal anaconda
builds
more bugfixes.  Still completely impossible for me to run local tests
now the only failure I'm aware of is due to incorrect astropy version
reporting (on my machine?)
last ugly doctest skip
more hacks, this time for incorrect signs in hms/dms
Merge pull request #240 from keflavich/just_class_refactor

Besancon reader repairs
NRAO table parsing fix, along with regression test

Adapt to new format of IRSA dust service responses (issue 241). Fix some tests and comments.
Merge pull request #244 from dshiga/issue-241

Fix irsa_dust to handle new format of dust service responses
fixes #245 - change 'extinction' argument to 'temperature'.
Update docs to reflect change of 'extinction' to 'temperature' (issue-245).
added the get_votable_fields script originally created by Madhura
this is not intended for user use, but can be used to regenerate the
.json file if it's updated
the JSON file is now sorted
oops, unbreak tests
Merge pull request #245 from dshiga/issue-245

'extinction' incorrectly maps to temperature section of irsa_dust result
refactor _is_coordinate / _is_name tests to common location, and avoid
issue astropy#1727
