Hirshfeld and Voronoi in xml
This is a feature request.
The atomic populations can be computed with Mulliken, Hirshfeld and Voronoi methods. The Mulliken charges are written to .xml file, while the output of the real-space-based method is not written to .xml file. It would be nice to extend the data written to .xml file.
I understand that .xml format is not as popular nowadays. Some other formats such as yaml or json would do. JSON is preferred format currently, right?
