Feature Parity Matrix

[tmc]

We should take inspiration (and content) from https://langchain.com/features.html and have a markdown file that indicates the current implementation state.

Once we have docs site (#21) this content could go there.

@rdbell Thanks, I moved that content to just be the issue description, we can use this to maintain the parity matrix (for now -- I do want this in source code / on a/the docs site).

May I ask if langchain.vectorstores.chroma should also be in this list, or is that implied in "Chat Vector DB Chain"? And When its ticked done, is that when its in the "exp" folder or needs to be moved out once complete? Just feeling out to see if I can contribute anywhere, and this is a handy grid to assess :)

I think we can have green checks and "(exp)" for implementations in exp.
