more MKE info on camera.owl

appending this to camera.mkr

do print od "<!--  equivalences  -->" done;
f-stop is ?;
focal-length is ?;


yields this additional output

<!--  equivalences  -->
[aperture is f-stop] iss owl:DatatypeProperty with unknown differentia;
[focal-length is size] iss owl:DatatypeProperty with unknown differentia;


My point being:
You can get lots of user-friendly output from MKE.
Just tell MKE what you want with the MKR script!
