Olm is designed to be easy port to different platforms and to be easy

to write bindings for.

It was originally implemented in C++, with a plain-C layer providing the public

API. As development has progressed, it has become clear that C++ gives little

advantage, and new functionality is being added in C, with C++ parts being

rewritten as the need ariases.
