This is a set of three directives that allow us to insert metadata
about doctests into the .rst files so the testing framework knows
which tests to skip.
This is quite different from the doctest extension in Sphinx itself,
which actually does something. For astropy, all of the testing is
centrally managed from py.test and Sphinx is not used for running
tests.
