[Therion] Exclude line parts in XVI export

[Torsten Schnitter]

Hi Stacho

The process of surveying an under water cave is (sometimes) like this:
- install survey line (as the navigational line is not suitable for doing survey)
- measure the line (stick map)
- do side measurements
- remove the survey line

As the existing navigational line is sometimes not usable for survey you have to install your own survey line.
But as the cave is visited frequently by many divers you have to remove your survey line again as soon as possible. Usualy there should be only one line inside an under water cave for having an absolute clear navigation.

Unfortunately sometimes you have to resurvey a part of the line. E.g. when some side messurements are missing or even don't make sense.
But as the original survey line is not in place anymore and therefore also the survey stations are not, you have to install a new survey line and redo the survey.
Of course you have to start at a well known station and also end at a well know station to connect the "new" survey correctly to the existing one.

Well, I presume I have to use the comment command to exclude all duplicate stations.

Especially assuming you need entire centerline including splay shots to draw a map. Could you please describe your workflow in detail to consider an appropriate solution?
