Progress: begin overhauling the printing infrastructure.
As part of making the level_3 projects (aka programs) more consistent, I started centralizing the print functions.
This started with status/error handling.
Then one thing led to the next and I ended up deciding to change the behavior to use file descriptors more consistently everywhere in the FLL project.
I also decided to go with the error print structure I original created in the fake program.
Verbosity has been moved into this structure.
The new level_2 project "fll_error" will store the error messages that are shared between the level_3 projects.
Given the size of these changes, I didn't complete the work.
This commit is guaranteed to not compile.
