Octree geometry seems to not work

[pepsuncho]

In some of my old input files (<2015) i have used the Octree geometry, which worked pretty well. Now i wanted to use it again (with exactly the same input file), but it was not working (using the 2020 release of EGSnrc). After that i have tried also the example geometries (octree-car/octree-sphere) and they seem also not to work. I get the following for the octree-geometry (octree-sphere):

type = EGS_Octree name = my_octree number of regions = 1 bounding box minimum = -1 -1 -1 bounding box maximum = 1 1 1 bounding box resolution = 32 32 32 octree leaf size = 0.0625 0.0625 0.0625 octree cells (no medium) = 1 octree cells (medium) = 0 octree average cell size = -nan octree cell savings = -nan%

Am i missing something, or the functionality of the octree-geometry is broken?

I've gone back to the start of the git version tracking (2015) and it seems the issue has existed since then. I guess we don't use the octree often! So you aren't missing anything - it does seem to be broken. I'll look into it...

Indeed, I never completely finished the octree geometry (in terms of proper testing and polishing up the input interface for it). I will also look at it to see what has happened since the original implementation.
