Generate the docstrings in _wcs.so using character arrays rather than
string literals.  This is (reportedly) more portable and avoid the
copying nonsense we did before.
Use `\overset{\circ}A` for Angstrom LaTeX.
Add subok and other np.array parameters
subok also for __quantity_view__, __quantity_instance__; more tests
Propagation of __quantity_view__, instance__ to subclasses
Simplify Quantity subclassing API, replacing __quantity_view__ and
__quantity_instance__ with __quantity_subclass__ and __quantity_finalize__.
Simplify _new_view, _new_instance further, remove __quantity_finalize__
Further simplification, using only _new_view
Simplify __quantity_subclass__ a little
Add tests for quantity.view; use _unit in __array_finalize__
Pass unit through Unit (fast if UnitBase already); use to simplify further
Add a brief summary about how to subclass quantity to the documentaion
Update subclass documentation following comments from @eteq
Further update to quantity subclassing documentation
Introducing main-docs-only option for automod api to be used in astropy.io.fits documentation.
Fixing bug in test_automodapi.py
Introduce a simple EarthLocation class, subclassed from CartesianPoints
Includes erfa gc2gd so that one can transform XYZ to geodetic
Use location exclusively, deprecating lon and lat (and removing height)
Move conversion of u, v, to "km" to inside the call to erfa
Insert available ellipoids in docstrings by hand
(formatting seems not possible for class methods in python2)
