Class lsst::utils::python::PySharedPtr

template<typename T>
class PySharedPtr

A shared pointer that tracks both a C++ object and its associated PyObject.

Each group of PySharedPtr for a given object collectively counts as one reference to that object for the purpose of Python garbage collection.

A PySharedPtr is implicitly convertible to and from a std::shared_ptr to minimize API impact. Any shared_ptr created this way will (I think) keep the Python reference alive, as described above.
