- Third version revised A. Fixed incorrect name of the package.
- Third version revised B. Changed the names of the modules so that now they are not ambiguous with those analogous ones from the deprecated package phonetic-languages-constaints.
- Third version revised C. Fixed issue with inner unneeded sorting and nubbing in the readMaybeEC function.
- Fourth version. Switched to more general subG functionality using InsertLeft class and instances. Added, therefore, additional dependencies.
