2.3.0

Added

• val3dity can now be compiled as a library and easily used in other C++ binary (it's GPLv3 license, watch out)
• this allows val3dity to be used with Python now, see https://github.com/tudelft3d/val3ditypy/
• unit test for IndoorGML files
• support for the simple format tu3djson (https://github.com/tudelft3d/tu3djson)

Changed

• fixed a few bugs for the parsing of IndoorGML files
• LoDs of Buildings are now taken into account when validating the topological relationships between BuildingParts: the tests are now per LoD now (so no "clash" between LoD1.3 and LoD2.2 if stored in the same file)

Removed

• removed the support for CityGML files and 'vanilla' GML files. Only IndoorGML files can be read, and support for GML 3.3 is not fully there yet. Most errors/issues that are reported with val3dity have to do with a faulty parser of CityGML, and not with val3dity itself. I cannot justify spending 100s of hours fixing the parser, I tried hard but this not possible anymore. If someone wants to do it then great I am willing to help them, but I will not invest time on this anymore. Just upgrade your files to CityJSON (https://www.cityjson.org/tutorials/conversion/), I'll always maintain a full CityJSON parser!
