 'x', 'y', 'z' are spatial co-ordinates, given in units of  (0.1 micrometers).
'diameter' is dendrite thickness, also given in  units of  (0.1 micrometers).

Note that sample connectivity is implicit in the data - after a termination point, the next point in the data is connected to the first incomplete binary branch point encountered when ascending the tree hierarchy.
