Create Docs for Liger-Kernel

[ParagEkbote]

Summary

Fixes #64

Instead of using Sphinx which I found to be cumbersome to set-up and iterate upon, I have created the docs using Material for Markdown, which uses markdown files for pages and does not change the original markdown files to a greater extent.

To preview in your local system: run make serve in the terminal.

To build pages: run make build in the terminal.

Please let me know if any styling or further corrections are needed and I will make the necessary changes.

Hi @ParagEkbote! Sorry for the very late reply since we were focusing on something else. Thank you for the great work and i will try to merge it in 2 days. Can you join our slack channel https://join.slack.com/t/ligerkernel/shared_invite/zt-2yavnspqs-0AYy5jduuxd1GKMGlKgFTw? cc @hebiao064

The docs looks good to me, please add mkdocs and mkdocs-material into setup.py otherwise other user won't be able to run make serve and make build

Error would be like:
bash: mkdocs: command not found without mkdocs

Error: MkDocs encountered an error parsing the configuration file: while constructing a Python object cannot find module 'pymdownx.superfences' (No module named 'pymdownx') without mkdocs-material

Discussed with @ByronHsu, let's merge this nice PR first and we will fix the setup.py
