[CM] On FFI bindings

I have several C extensions i've written, and i give all of them an entry point with this prototype

void install_scheme_objects(s7_scheme *s);

then, I load those extensions with

(load filename (sublet (curlet) 'init_func 'install_scheme_objects))

the install_scheme_objects function usually sets up an envrionment and adds its functions there

Hope this helps,
Woody Douglass

Hi all,
In my s7-imgui project I have bindings for some different libraries.
- to get an open/save dialog
- GUI functionality
- std <regex> (C++11) operations
and so on. Soon I'd like to make each of these bindings a dynamic library where one could load like (load-extension ..) and get acces to these bindings.
I think it'd be good to decide on a suggested API for these. How one should provide an s7 environment via a C API.
