Example python extension using pybind11 and an 'external' shared lib
note that the python_example/ subdir is copied (largely) from the pybind11 repo and therefore carries the original source license from pybind11.
the toy library libherpderp.so is a stand-in for some arbitrary pre-compiled .so to use this example, you must first build libherpderp.so by running 'make' in the herpderp/ directory
