Direction of Cross Sections #22

Currently you have the cross section as perpendicular to the last leg. If it is a station with a single leg, that is the only real automatic option. However. when there are 2 legs, the most common definition and the one that gets it right most often is the perpendicular bisector of the legs. This is what pockettopo, Therion and I believe Survex all use, so it would make sense to use the same as the programme they are likely to be exported to.

I really like the lines showing where the cross sections are, a real nifty feature would be to allow the user to set the direction. Guess some thought would have to be put into how the direction is exported, but I and others have used the direction you are facing in bracket after the station number, when doing this on paper surveying, so maybe this could be adapted

It would be nice to add a directional arrow to the cross section line at least.
