Example statements

This PR is still under development. When completed it will:

* Swap appendix C and D round so that appendix C contains the example statements
* Add an example statement to appendix C that contains every property (where legal)
* Add a new appendix D (and reshuffle the current D, E and F) for examples of the different objectTypes that can be used as the object of the statement. 

Please comment now if you think any other examples should be added.
