Based on: https://paulbourke.net/fractals/bioblob/
Done, by brute force, in Nim. The program exports a POV-Ray scene with spheres
or in include file with an array of arrays array[6]{centerX, centerY, centerZ,
radius, parent, generation}, of whitch the skeleton is made.
Now working slowly on speed improvement (R-TreeD?) and ideas to influce the
growth. Wind, gravity, interaction with a container o other growths (forrest(?)

The R-Tree3D works:
spheretests is how many new spheres it tried to place.\
placementTest is the amount of sphere sphere intersection tests. A child sphere
should only intersect with its parent. the Tree makes quite a difference here
