Hi Marco, As far as I'm aware of, such a tool does not exist. But maybe some of the other users have been very busy.
As for point two, I'm not a developer, so I don't know what's in the pipeline. The structure classes, using the scheme interface, are not implemented in MEEP itself, they are implemented using libctl. If you look at the utils folder in the libctl directory you'll find the source code. Adding a new geometric object would involve coding some c++ and Scheme, but the code for the current structures can be guide. An alternative would be using the c++ interface where you have more control on how you define your structure (you'll need to define a function that describes your structure), however the sub pixel averaging in the c-interface is not as accurate / fast as the one used in the Scheme interface.
