added folder and initial files for the splatalogue search API
fixed besancon example
added besancon & nist tests
added tests for magpis, nrao, simbad, vizier - right now, they're all
just copies of the doctests, but they should be a seed for future tests
default tests for all NED functions
fixed some tests, and added atpy as a requirement (it is needed for NED)
test bugfixes
added nist docs; why was this untracked?
NED docs added/fixed (not really clear which because of weirdness with branches)
Merge pull request #33 from keflavich/tests_and_docs

Tests and docs
Tests fail, but they were failing anyway, so I don't think it hurts to have more tests.  Also, docs are needed.  And merging without this in master will be a pain.
added besancon reader (originally written for astropy; depends on
astropy)
included besancon reader test in test_besancon
added asciitable to travis (besancon still depends on it)
bugfix; had an erroneous and extraneous line
import besancon reader correctly
moved around .txt file for besancon test; for some reason it can't find
the file?!
Merge pull request #34 from keflavich/besancon_reader

Besancon reader
(required for tests, so I'm going to merge it and deal with errors later)
various tweaks and fixes
Fix and format code example in README
Fix errors and warnings pointed out by Eclipse PyDev code analysis

Mostly unused imports and variables, non-standard indentation.
Some real errors.
Should be clear what the problem was from the diff.
