new version of xlw available, used by QuantLibXL

[Ferdinando M. Ametrano-2]

Hi all

version 1.2 of xlw (http://xlw.sf.net) has been released. xlw is a nice
tool to export analytics to Excel and it is currently used for QuantLibXL.
While I expect some big news on this issues in the next weeks version 1.2
might be worth your time if you're into C++->Excel
