Updated package.json.
Remove article dependency.
Bump.
Make writer aware of views.
Straightened seeding.
Add an option for Annotator to enable co-transformations.

It turned out, that it is necessary to explicitely commit changes to the
ranges, as otherwise annotations would not get updated properly
using undo/redo.

Co-transformations are now enabled only in simulations
to avoid duplicate changes.
Activate Annotator co-transformations when starting document simulations.
Delete annoations correctly when target gets deleted.
Fix regression.
More efficient document simulation (aka transactions) using Chronicle.
Improved simulation impl.
Use same transaction for deleting in modifyNode.
Proper cursor validity check.
Removed obsolete test.
Adding (unit) tests.
Simplified and renamed 'position'.

It is now 'show' - the pendant of 'hide'.
Removed the re-positioning logic, as it turned out to be erronous
and has been kind of over-engineered.
Now the caller has the responsibility to hide elements first if
he wants to reposition them.
Not a real change.
First iteration on reactivating copy'n'paste.

Not yet working.
Solid integrity checks for setting cursor.
More robustness for show and hide.
