	/* TODO: Implement remote holon import (e.g. from another server like
	holon1@bla.foi.hr). The import statement needs to be changed
	to something like: from holon1 import output1 as h1out
	or from holon2@rec.foi.hr import * (similar to Python
	syntax), since if a holon has multiple inputs or outputs
	we need a way to differentiate between them. Also to avoid
	possible nameclashes we should use "as" as a way to rename
	the symbols for local use. */
