v1.0 of val3dity is released

Today I'm happy to release officially the v1.0 of val3dity: my code to validate 3D geometries (solids, composite- and multi-surface).

I started in 2010 to work on it (thanks to a sponsorship from Safe Software), and I've been working on it part-time since then.
Through an OGC CityGML Quality Interoperability Experiment (QIE), I've tested and improved it a lot the last few months.
It's now mature, robust and complete enough to be used by anyone.
