adding a .gitignore file

[surchs]

Hey, great repo. I noticed that you have a .DS file in your repository. Most likely that came over when committed all files in the repository and then made a push from a Mac computer. If you want to keep files like these out of you repository, you can use a .gitignore file that you add to the top of your github repository. This can also be helpful when you use a text editor or IDE that creates local configuration files that you don't want to upload to your repository.

Hi @surchs! Thank you so much for this suggestion! I was wondering what the .DS file was. Would the .ipynb_checkpoints directory also be something to include in the .gitignore file? Is that what you mean by a text editor/IDE creating local configuration files?

[surchs]

Yeah exactly. The ipynb checkpoints could also go in there. If you google around a bit you may find some nice .gitignore templates for python projects or those using notebooks.
