Bindings for normal and reference MEMVARs. Currently doesn't yet include PTR, SHARED_PTR, and ATOMIC versions.

This all looks great. I think it needs three things to be complete:

1. Completeness: Finish macros for the other types of MEMVARs. I know it's easy to stop with the ones that we're actively using, but since this is a finite and stable set of things to include, and has a pretty consistent pattern, I'd really like to see the remaining items included.
2. Documentation: The header file needs some documentation on how to use it. Preferrably this would be in a doxygen-compatible way for the file. As an example, check out Utility/MemberVariable.hh.
3. Unit testing: I suggest a simple test where you create a C++ class that uses a each of the MEMVAR macros (at least one of each type, i.e. normal, ref, ptr, shared_ptr, and atomic), bind them with the macro, and then in the test demonstrate that you can access the properties in python.
