[santacodes]

• Added git initialisation hooks in the template to automatically initialise a git repository when a generated project is created by cookiecutter.
• Added a default main branch parameter for git repository initialisation.

Looks good, thanks @santacodes! I haven't tested this locally but could you confirm if this is working locally?

Thanks, @santacodes! While I shall approve this PR now so that it gets your other PR going, I would suggest that we provide an option in the template to not require hatch-vcs by default. Making this it an opt-in piece of functionality would be great, this way, this script would not be needed for installing the package. Moreover, I feel that new users of PyBaMM and newcomers to Python packaging would like to hardcode the package version in a string instead of trying to wrap their heads around version control systems.

Yes it does, I tested it locally before pushing it.

I completely agree, I will add a new prompt for that to opt-in hatch-vcs and make it false by default so that they don't have to go through that hassle. Perhaps as you said the versions could be hardcoded in the _version.py file and can be configured through tool.hatch.version. I am working on the patch and will push that commit in #29, it should possibly resolve all the failing tests as well. Thank you for the insights!

Works well, I'd now need to re-configure my git name & mail 😆
