Fix 'r' key to properly find an open node when the active node is tagged,
or when a node had tags additionally to tags that mean "end".
tree_util: avoid creating a new list for no reason.
Remove print statement.
Handle potential errors when invoking createPresynapticTreenode.
NeuroML Level3 1.8.1 exporter may be a bit less bad. Loads into neuroConstruct.
skeletonexport: sanitize argument for SQL command.
export_NeuroML_Level3: fix error whereby many segments were skipped.
SVGOverlay.editRadius remembers last option and refreshes nodes.
neuroml 1.8.1: fix error when exporting an arbor whose root node is a branch.
webglapp: reuse geometry for node radiuses, enabling the rendering
of large neurons with many of its nodes having a radius set.
SVGOverlay: created staticMoveToAndSelectNode
webglapp: two consecutive treenodes with a defined radius will be shown as a cylinder
having as radius that of the child node.
Treeodes with a defined radius but without a radius in the parent or child
will be shown as spheres.
And these spheres and cylinders are shift+clickable to jump to the node in the canvas.

Additionally, the spheres are now icospheres with subdivision 2, with reused geometry throughout.
Cylinders also reuse geometry.
webglapp: use less memory, no need for orig_coord object or skeleton_id in every mesh.
Also reuse the pixel space vectors when possible--less multiplications.
webglapp: color cylinders and spheres with centrality weighting when required.

Removes the need for a new instance of a BasicMeshMaterial for every node.
neuroml export: add ability to export a single neuron with selected sets of input partners
represented not with morphology but as input sources.
Remove white space and correct a typo in documentation.
added stack orientation (xy:default,yz,zy) as a field to stack
coordinate transfer from and into project coordinates respect this
orientation
pure stack navigation with re-oriented static stacks working
added vertical and horizontal middle line to stack
moved orientation field from stack to projectstack relation as it
specifies the orientation of a stack relative to a project
even better help and disclaimer icons, still not happy with the slightly
magenta blue (why is that so?  I am generating them with 0000ff blue,
0 transparency!)
