"""
This file will automaticcaly create the cpp files for the parsers for pod and std::containers of pods, and some other maps

This reduces the maximum required memory and allows faster compilation due to higher parallelisation of the build process
This needs only to be run if additional parsers are neccessary.
In this case copy the file to DDCore/src/parsers and run the program.
