Fix/broken getting started link (#511)

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)

Readme typos (#409)

add sqlalchemy generic cache (#361) 
Created a generic SQLAlchemyCache class to plug any database supported
by SQAlchemy. (I am using Postgres).
I also based the class SQLiteCache class on this class SQLAlchemyCache.

As a side note, I'm questioning the need for two distinct class
LLMCache, FullLLMCache. Shouldn't we merge both ?

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.

Refine Olivia Wilde's boyfriend example prompt to work better (#248) 
With the original prompt, the chain keeps trying to jump straight to
doing math directly, without first looking up ages. With this two-part
question, it behaves more as intended:


> Entering new ZeroShotAgent chain...
How old is Olivia Wilde's boyfriend? What is that number raised to the
0.23 power?
Thought: I need to find out how old Olivia Wilde's boyfriend is, and
then use a calculator to calculate the power.
Action: Search
Action Input: Olivia Wilde's boyfriend age
Observation: While Wilde, 37, and Styles, 27, have both kept a low
profile when it comes to talking about their relationship, Wilde did
address their ...
Thought: Olivia Wilde's boyfriend is 27 years old.
Action: Calculator
Action Input: 27^0.23

> Entering new LLMMathChain chain...
27^0.23

```python
import math
print(math.pow(27, 0.23))
```

Answer: 2.1340945944237553

> Finished LLMMathChain chain.

Observation: Answer: 2.1340945944237553

Thought: I now know the final answer.

Add MemoryChain and ConversationChain as chains that take a docstore in
