These are just the passing test cases for the domains currently. I am going to
patch up issues with nesting on both domains to start, so these are the test
cases I'll be testing against. I'll see about addressing the other core
domains, or at very least the cpp domain, with similar tests if this looks
okay.
So far, these tests only test against methods/functions for the basic nesting
structure. More complete tests will test additional domain roles.
Refs #662
* rename a few test modules to make the names more consistent
* do not copy/use Sphinx from build/ (unnecessary without 2to3)
* use a temporary dir for *all* test projects, the source tree
will stay pristine that way (default is tests/build)
* speed up tests by ~3x by splitting up test projects and avoiding
rebuilds
