Regressions pass! With a few tweaks for unsupported features, primarily:

- Throwing wrapped types as exceptions is unsupported.
- Reverse comparison operators (e.g., __radd__) aren't supported.

Rationalized destructors.

Finished std::map implementation.  Required fixes to typecheck for
SWIGTYPE* const&.

Need a little special handling of the swig_type_info for SwigPyObject
when multiple modules are loaded.

Fall back to SwigPyObject_richcompare if there's no operator overload.

"memberget" and "memberset" attrs are applied strangely; work around
them.

Added 'this' attribute.
