this has abstractions for getting the names.json file and reading them
and parsing them. i also moved the cli logger initialization code into
its own module.
the cli now uses a new module in the shared crate, called directories
which is a module that has functions for directory stuff, mainly, it
uses the directories crate to have a portable way to have directories
for the application like data directories and config directories.
i also added logging to the shared and cli crates, so you can see debug
stuff with the RUST_LOG environment variable.
