added pytest.ini with doctests
added bs4 dependency, skip some tests...
dependencies & imports
notes about vizier tests
bs4 -> beautifulsoup4
vo pip fix; I think vo is only required because of atpy.  Everything
should transition to astropy.table, but there are some incompatibilities
at the moment
astrolib routines aren't on pip =(
another stsci/astrolib package
trivial typo
tried to fix some tests.  Besancon tests are broken, but that's because
of the besancon branch.  I think I need to merge that branch before I
can get anywhere with tests in general
mocks for readthedocs
fixed SIMBAD examples per cdeil's findings
overwrite=True in magpis tests to avoid boring "file already exists"
error
added code-block markup
