Added .prettierignore - What about Prettier support?

[tonix-tuft]

I have forked your repo and as I am using Prettier with VS Code and it automatically formats code code on save, I had to add a .prettierignore file.
I guess other devs use Prettier too nowadays, so I think it would be great if the project supported it as well.

For now, the .prettierignore file ignores all the files within the src directory, but as soon as we enable Prettier, I will change that and the files will be automatically formatted on save (provided that the editor supports the format on save option, VS Code does).

If you are using VS Code, you can install Prettier by Esben Petersen (the first one with 6.1M downloads):

And configure VS Code in your Settings:

Then we can add a .prettierrc file containing all the formatting rules conventions for this specific project.

What do you think?
