New version of QiQA prototype

After a few weeks of hard work, the core of the "Quick Quotation Assistant" (QiQA) prototype was redesigned from scratch. Although the interface remains unchanged (except for a minor detail on QiQA-Builder) the implementation of algorithms is now absolutely different. These are now independent from each other, whilst in the previous version all were implemented together,with several cross-dependencies and lots of unnecessary functionalities. The current version of the prototype and a small drawing collection are available at the QiQA software download page.
