New Codebase, Better Optimization

This release was built from code ported from the original C to C++, a process begun by Mike Nordell back in 2000. Extensive code cleanup and bug-fixing has continued, along with new memory management and language enhancements. Not least, during the v.1.5 development process, the SQL query optimizer has undergone enhancements and fixes at the hands of Arno Brinkman and others, resulting in reported speed improvement of 30 to 60 percent and more.
