This issue should not be started until all other afw wrapping issues are merged, so that it can clean up any tests that slipped through the cracks.

I think we are ready for this now.

I found four tests that needed attention:

• A skip in testFunction.py
• A skip in testSpatialCell.py
• testTableMultiMatch.py which was not in test.txt
• testSpherePoint.py which was not in test.txt

Tests I did not change but have skips:

• The skip in testHeavyFootprint.py looks permanent. We should remove that test at some point, but I did not do it yet.
• The skip in testSourceTable.py is fixed in DM-8751.

I enabled the skipped test in testFunction.py. In the process I found some errors in the C++ that I fixed (on a separate commit), including:

• IntegerDeltaFunction1::operator() took two arguments instead of one and ignored the second. Apparently we've never needed that function, but I'd rather it be fixed now and we can decide later whether to get rid of it.
• Many functions classes were not being instantiated. Our usual pattern is to instantiate all templated classes we expect to use in C++ or Python and apparently I messed up years ago.
• A typo in the pybind11 wrapper rendered clone unusable for one class.

I enabled the skipped test in testSpatialCell.py.

I also standardized the code in spacialCell.cc to not use pybind11/operators.h and to use namespaces in the usual way. I also added functions to declare classes because it declares so many classes. I felt it made the code significantly more readable.

I wrapped SpherePoint and thus fixed testSpherePoint.py.

I fixed testTableMultiMatch.py. This test turned up several issues, including:

• SchemaMapper.editOutputSchema was incorrectly wrapped. The returned value was not a reference, so modifying it did not have the desired affect.
• Column views were incorrectly wrapped (every table has its own type).
• Schema was missing a useful string representation. I added Schema.__repr__. In SWIG the __str__ was identical so I omitted it (since str is used if repr not found). I can add it if desired (and I admit we usually do, but I'm not sure why).
