Description

I am looking at using Gandiva's Python bindings in an experimental project, and noticed there aren't any Sphinx docs. Assuming it's not too early, I would be willing to add documentation in Sphinx.

Two starting points for documentation:

• A how-to for creating filters and projections using the builders. The first part of this blog post gives the right idea: https://blog.christianperone.com/2020/01/gandiva-using-llvm-and-arrow-to-jit-and-evaluate-pandas-expressions/
• API reference. If possible, it would be cool to have a table listing all of the available functions in the registry.
