Previously, much of the logic for generating the various objects needed for fuzzing was concentrated primarily in `generators.rs`. In trying to piece together what code does what, the size of the file and the light documentation make it hard to discern what each part does. Since several generator structures had been split out as separate modules in the `generators/` directory, this change takes that refactoring further by moving the structures in `generators.rs` to their own modules. No logic changes were made, only the addition of documentation in a few places.
