+This utility script helps in the creation of experiment setups. It therefore
+reads experiment descriptions from json files and creates everything necessary
+as a result.
+
+It therefore performs the following actions:
+* [x] Read the json file of every experiment
+* [x] Create folders for every experiment
+* [ ] Create the header file for every experiment
+* [x] Add the make file for every experiment
+* [x] Add c++ file for every experiment
