Added BigRational class.

Very occasionally there have been some floating point precision issues with the polygon boolean operations. Triangulation has been more stable, though problems possibly can occur there too. So to provide a robust option, WW.Math (and thus also CadLib) now includes a BigRational class, and exact arithmetic versions of the polygon boolean operations and 2D triangulation. See namespace WW.Math.Exact and WW.Math.Exact.Geometry. Speed could be a lot better, but unfortunately C# misses some low level features. Also some in the future some faster algorithms will be used.
