Easy to Get Stats?

[StevenCarleton]

Would be nice to have a quick way to record game stats like oil points spent, units purchased, etc. without have to write down all that data.
Tried saving each turn in .data files in Hotseat mode, and then comparing files between turns, but it looks like Johan is serializing the entire object tree in binary format, so the .data files aren't easy to parse.
Perhaps there's some undocumented method used in debug mode?
We could use this for our AARs and for spotting dangerous trends during game play.
