#12 Create output in XML or TXT for results analysis

[Yoann Jagoury]

For both the console and the GUI version:
In order to improve the tuning of trader results and
analyse where those traders do well or bad, create
output (XML, CSV, TXT ?) that can be used to track the
date, current price, current position, realised PnL,
unrealised PnL.
This data should allow to have a vision per day of the
trader situation.
