Update project status in README and gitignore

Housekeeping:

- Gotta let everyone know i'm back on my bs.

- Also gotta make *.out files not show up in `git status`, so add on a c
language gitignore template to existing `.gitignore` and integrate.

+For the most part I'm just typing in things from the book and adding comments to help me understand the code while reading and updating style to make code lint clean.
