Standardize repo into the same practices as core mesa repo

[jackiekazil]

We want to make sure that this repo matches the practices of https://github.com/projectmesa/mesa. Here is a checklist. I am sure I forgot things, so please add them as you see fit.

• Add issue template
• Add CI/CD
• Add discussions
• Convert to rebase to PRs
• Get PyPI access for deployments
• Create a Read the Docs
• Add cookiecutter

Anything else?

[rht]

• Rename master to main

[rht]

• Add code of conduct
• Update license year
• Add CONTRIBUTING.rst
• Add CITATION.bib (but I figured that there is no publication on Mesa-Geo yet?)

• Add CITATION.bib (but I figured that there is no publication on Mesa-Geo yet?)

That's right! But I'm working on it at the moment.

There are two remaining items:

• Add CI/CD

Currently the CI/CD of Mesa-Geo is pretty much the same as that of Mesa.

• Add cookiecutter

Do we really need a separate template for Mesa-Geo? Perhaps mesa startproject is already sufficient?

If not shall we go ahead and close this ticket?

[jackiekazil]

since I have been in the cookiecutter stuff recently -- I would like to take a few minutes today to consider the last item.

We need more improvements in general in our CI/CD, but if it the same as the main project, then that is what we are looking for at this time.

Having a separate template for Mesa-Geo might be a good idea - to have a template that creates GeoAgent and uses GeoSpace in models.

Have created #133 for this.
