```
    Calculates the name of the new version that will be created by a checkin call. The name is determined as follows:
    - first the predecessor version with the shortest name is searched.
    - if that predecessor version is the root version, the new version gets the name "{number of successors}+1" + ".0"
    - if that predecessor version has no successor, the last digit of it's version number is incremented.
    - if that predecessor version has successors but the incremented name does not exist, that name is used.
    - otherwise a ".0" is added to the name until a non conflicting name is found.
