Release 0.0.0.9120

This release addresses a build failure in the previous release due to a improper class creation.

The user documentation ready4use_user_0.0.0.9120.pdf is the manual that is recommended for most package users as it lists only functions intended for use. There is an extended version of the manual ready4use_developer_0.0.0.9120.pdf that provides a full list of all functions in the package (potentially including buggy, poorly tested in development functions or helper functions not meant for end-users), but this is only potentially useful for developers who want a quick guide to what's under the hood.
