Docs, headerfiles, and all that

[piyush-kurur]

While we have mostly used verse to generate code, it would be good if the verse also generates some
minimal documentation and header files for easy integration with outside projects. Here I collect some of
these information that can be useful.

• Doxygen or some other documentation
• Function prototypes
• Header files
• Somehow lift the names in Coq source to names in C code. Might need some tactics
• For assembly code, annotate with the corresponding verse instruction.
• Frama-C annotations for safety of the generated C functions.
