When a user creates an offer (has to make a deposit first)

The issue is that make a withdraw when a offer is in place, so to solve it, when the offer is created, the smart contract should move the balance to lock balance.

There is some file on the test directory that has .bak termination, they are the old test methods.

The task is to get the general information of those tests methods and update them in a more organized way (as the ones that just end with .js)

Start with the daoreg test, because daoinfo is a bit more tricky and need background of the document - graph library

Information about the delphi oracle can be found at: https://github.com/eostitan/delphioracle

The order book has two system tokens TLOS and USD (currently only TLOS), we need to add the oracle to retrieve information of the current value of USD/TLOS.

• The user may enter the price in TLOS or USD. If the price is in USD, the exchange contract must use the delphi oracle contract to query the TLOS/USD price for evaluation.

Users may trade DAO tokens with the TLOS token

Order Making/Creating

• Users may create an order to purchase the DAO token
• To create a buy order, the user must first transfer TLOS tokens to the exchange smart contract
• When creating a buy order, the user enters the asset/quantity to purchase and the price
• The user may enter the price in TLOS or USD. If the price is in USD, the exchange contract must use the delphi oracle contract to query the TLOS/USD price for evaluation.
• To create a sell order, the user must first transfer their DAO tokens ("LAND") to the exchange smart contract
• When creating a sell order, the user enters the asset/quantity to buy and the price (the user may enter the price in TLOS or USD)

Order Taking/Accepting

• Users may take (or accept) any open orders
• The user must have a balance of the counter-token
• Partial order fills are OK
• When an order is filled, the contract sends the appropriate token amounts to the appropriate traders
• No fees for now

Order Matching

• Order matching is when a new "make" order is created with a price that is able to match with an existing open order.
• In these cases, the order should be executed at the price of the existing (first) open order.
• This functionality opens the ability for "market orders", but we do not need to support this yet.
