[Therion] data nosurvey

[Andrew Atkinson]

Yep, that would work, but Therion is meant to work with the survex data 
formats, so the nosurvey should work. It looks a bit like a bug, or I am 
using wrongly. If no survey is not supported, that is fine, it is not 
critical.

My solution would be to put a false leg in and not that nearly hit and 
accept a small gap. This would not case any false distortion but I 
prefer the idea of nosurvey.
