[Therion] New Therion tips on wiki

Martin S I like your tip on straightening out zig-zig survey legs in passages in order to make extended elevations more realistic. https://therion.speleo.sk/wiki/doku.php/tips?s[]=zig <https://therion.speleo.sk/wiki/doku.php/tips?s%5b%5d=zig&s%5b%5d=zag> &s[]=zag I am sure I will use that. Also notice you have added a link to an executable for converting maps to data. Is there a page or some information about what it is and how it works? Some might be nervous about downloading an executable directly without any explanation about what it is and how it works (in case it is malware) Bruce PS New look wiki looks good.
