Add [source] to RTD

[seanlaw]

Recently, I learned about the sphinx linkcode extension for adding [source] references within docstrings (example).

Hi @seanlaw!
I'd love to take this issue on as my first contribution here.
I can update the Sphinx configuration (typically adding 'sphinx.ext.viewcode' to the extensions list in docs/conf.py) to ensure the [source] links render correctly on Read the Docs.
Could you please assign this to me?

@Brownteen18 Thank you for your interest. When I look at at the API reference I am already seeing [source] for the functions. I think this is no longer needed.
