add tracing support to langchain (#741) 
* add implementations of `BaseCallbackHandler` to support tracing:
`SharedTracer` which is thread-safe and `Tracer` which is not and is
meant to be used locally.
* Tracers persist runs to locally running `langchain-server`

Docs refactor (#480) 
Big docs refactor! Motivation is to make it easier for people to find
resources they are looking for. To accomplish this, there are now three
main sections:

- Getting Started: steps for getting started, walking through most core
functionality
- Modules: these are different modules of functionality that langchain
provides. Each part here has a "getting started", "how to", "key
concepts" and "reference" section (except in a few select cases where it
didnt easily fit).
- Use Cases: this is to separate use cases (like summarization, question
answering, evaluation, etc) from the modules, and provide a different
entry point to the code base.

There is also a full reference section, as well as extra resources
(glossary, gallery, etc)

Add LLMCheckerChain (#281) 
Implementation of https://github.com/jagilley/fact-checker. Works pretty
well.

<img width="993" alt="Screenshot 2022-12-07 at 4 41 47 PM"

Verifying this manually:
1. "Only two kinds of egg-laying mammals are left on the planet
today—the duck-billed platypus and the echidna, or spiny anteater."
https://www.scientificamerican.com/article/extreme-monotremes/
2. "An [Echidna] egg weighs 1.5 to 2 grams (0.05 to 0.07
oz)[[19]](https://en.wikipedia.org/wiki/Echidna#cite_note-19) and is
about 1.4 centimetres (0.55 in) long."
https://en.wikipedia.org/wiki/Echidna#:~:text=sleep%20is%20suppressed.-,Reproduction,a%20reptile%2Dlike%20egg%20tooth.
3. "A [platypus] lays one to three (usually two) small, leathery eggs
(similar to those of reptiles), about 11 mm (7⁄16 in) in diameter and
slightly rounder than bird eggs."
https://en.wikipedia.org/wiki/Platypus#:~:text=It%20lays%20one%20to%20three,slightly%20rounder%20than%20bird%20eggs.
4. Therefore, an Echidna is the mammal that lays the biggest eggs.

Love the project, a ton of fun!

I think the PR is pretty self-explanatory, happy to make any changes! I
am working on using it in an `LLMBashChain` and may update as that
progresses.

Adds support for statements such as insert, update etc which do not
