#16 NTTypes: public document is outdated

[Ralph Lange]

I am getting questions/complaints about the public NTTypes documentation on the web being only loosely related to the types mentioned in talks and trainings.

The link to normativeTypes.html points to an outdated version of 18-Oct-2012.

There are five (!) newer versions in the repository, none of which are linked appropriately onto the main index page.
