cpp branch

[Geert Janssens]

Bob,

I managed to work around the segfault I had left and pushed that commit as 
well in case you want to try it.

While doing so I noticed three more issues I need to fix:
- newlines are not properly stripped from csv type data (they are for fixed 
width type data)
- column splitting misbehaves with multi-byte characters (it can even split 
one right in the middle causing invalid characters
- invalid dates are not detected. This one will be fixed while porting to 
Johns GncNumeric code.

Just so you know where I am currently.

Regards,

Geert
