------------------
First version with real trading functionality. However **cointrader has no
working trading strategy yet**. So the default strategy will do nothing than
waiting :). However you can use the interactive mode to buy and sell coins if
you want to.
* Added automatic trading. Cointrader will follow the emitted signals from the
strategy.
* Added Papertrading. Do trading without any risk. Cointrader will simulate
trading.
* Added Tradelog.
