-working version;
-at the beginning every CO is connected to it's nearest
neighbor (with some 'natural' exceptions); only pairs of two are made;
from now, only an even number of COs will be generated;
-corrected a MAJOR BUG, where the GameObjects representing the COs
had two ConnectionObject scripts attached (one fron the prefab and
one given at instantiation (instead of GetComponent, I did an AddComponent))
