It, however, does not make any use of it, currently...

and various types of noise in the last simulation stage.
Additionally, the histogram is fine now. It is nearly the same as the
histogram of real images.

Tips are addressed as filoID+branchID (latter unique within only within its filopodium).

Ale the importer considers the skeleton segments ID as a guide for reliable filopodia tip tracking.

(which is a consequence of the new plan between GM and TM
that filopodia VTKs may not use sequential numbers in their
filenames... hence, if 04 fails to load, we cannot assume that
there is no 05..).

to determine size of the output images.

Generator, BUG: When Phases II and III are not required, texture image shouldn't be exported (its the same as phantom anyway).
