Convention on (ignored) file naming

[bagustris]

I added .gitignore several weeks ago. I see many untracked files (hundreds) in my VS code (source control bar) previously. Using this .gitignore file, now my Nkululeko is clean. As a result, this will ignore some (file/folder) patterns like

tests_*/ # eg dir tests_bagus
run_*  # eg file run_icassp2.sh, run_polish
exp_*/  # eg dir exp_cocosda2024
*.bak
*.orig
*_orig

If you need to commit a file name with the pattern included in .gitignore, you need to use argument -f when committing.

If you have other pattern to ignore, feel free to add them in .gitignore file.
