Documentation for Automated Market Makers Contracts

It's not clear how to use the Market makers we have designed for CT Framework. We have a great introduction to AMM with some good theoretical examples, but it's lacking code examples. The code examples we do have are in the LMSR tutorial but is abstracted a level above the smart contract to working with LMSR within Truffle.

I'd argue that for each market maker we should have instructions and examples for:
-> Deploying an instance of AMM
-> Use of each function with expected Happy/Unhappy returns

Start with the existing AMM introduction and LMSR tutorial, then review the market-maker contracts in the linked conditional-tokens-market-makers repository. For each market maker, document deployment and the functions' expected happy and unhappy returns, using the existing examples as a reference.
