-=== Further development ===
-
-The eendraadschema software is, and has been used by various hobbyists on the Belgian
-market. As such it is important that the software remains backwards compatible with
-all earlier generated EDS-files.
-
-Given that exports- and imports- of the schematics (EDS-file) are basically
-json-dumps of internal data-structures, until further notice, this entails the following:
-- No fundamental changes can be allowed to the data-model underlying the hierarchical trees that can be
-  drawn with the software, as embedded in the Hierarchical_List -class.
-- No fundamental changes can be allowed to the Electro_Item -class constructor. Especially the order of the
-  keys must be maintained. If new future features require an extension of the number of available keys,
-  extra keys should be added at the end.
