Establish good naming conventions
Currently, we tend to use the prefix F for formula-level things and the prefix N for natural language-level things (
NGrammar, ...). However, it is not used consistently.
Sometimes, functions are suffixed with their resulting type.
Sometimes, the names of functions are simply their signature.
- Establish a good naming convention (taking into account conventions used by the GF community).
- Enforce this naming conventions throughout the project.
