hi Ian,

yes, i guess the CartesianCoordinate thorn could work. this is not part of the ET, though, is it?

Hi Miguel,

You're right; I hadn't realised this. It's in the CTGamma arrangement:

https://bitbucket.org/llamacode/ctgamma/src/master/

but is not part of the toolkit. Just clone CTGamma into arrangements and add CTGamma/CartesianCoordinates to the thornlist and recompile.
