/*
This interface for now just deals with the working copy of the model,
versions in the storing (like revision control systems) are not supported/integrated,
needs a more general approach to input, synchronizer, changesets and such.
A model/document can be versioned if the changes to it are traced and reversable.
Addressing:
While we don't do a distributed model and concurrent changes we use simple
increasing indizes to address the different version, starting with 0.
The initial version as created/loaded in memory gets the index 0. All following
versions get a indexOfPrevious+1. This approach might be reusable for local
addressing later.
Wandering in the version "tree":
The model can be reset to a previous version, or be set
again to a newer version it had been advanced to before.
If the model was reset to a previous version and is changed, currently no branch is
created but all the versions that are newer are simply skipped.
