Overview

This PR is focused on making it more streamlined for people to contribute to HEXRD and engage with the library. In terms of content, this PR is split into two sections.

• 1 PR template

CONTRIBUTING.md

In addition to the changes here, we will lay out encouragement + instructions for contributing to HEXRD. This includes directing people to using the new issue templates introduced here, directing users to use issues, github discussion board, or the slack channels to share ideas and providing some simple workflow instructions for actually doing development.

Style Guide

Draft version -- https://github.com/Verdant-Evolution/hexrd/wiki/style-guide

The style guide provided here is a combination of existing well developed style guides, namely the PEP8 guidelines and the NumPy style guide. None of the guidelines enumerated in this guide are intended to change how well formatted development has been done on HEXRD, but is merely to lay out the guidelines and examples of what the code should look like for those that are not familiar with following a style guide.

In addition to particular code style, it includes:

1. Suggests that developers use pylint and provides a .pylintrc
2. Suggests that developers use typing and type checking with a reference to pyright and mypy
3. Instructs users to use black to format their code.

Affected Workflows

Technical workflows are unaffected. This only affects how users contribute to repo.

Documentation Changes

These changes are self-documenting and optional to engage with. A user can always select a blank issue template to fill out, or simply remove the auto-populated content of the PR if it is inappropriate.

Requested Feedback

I would appreciate any feedback you may have on the details of the templates as well as the changes to the Wiki.
I removed the Home.md from the wiki, since it was largely a contribution guide to begin with. If we should replace it with something, I am open to suggestions.
