Draws pointers away at random positive deflections of length ~llen
from nodes inodes in tree intree.
Pointer are offset by XYZ 3-tupel DD
and coloured with RGB 3-tupel color.
By default these are simple spheres.
With options '-l' or '-v' the pointers look a bit like
thin or thick electrodes respectively.
HP is the handle to the graphical object.
Example:
green spheres around nodes #8, #5 and #2
>> HP = pointer_tree (tree, [8 5 2], [], [0 1 0]);
red “patch” electrode on node #4
>> HP = pointer_tree (tree, 14, 100, [1 0 0], [], '-v');
blue transparent “sharp” electrode on node #15
>> HP = pointer_tree (tree, 15, 50, [0 0 1], [], '-l');
>> set (HP, 'facealpha',.1);
