Unfolding of an SFG

Description of issue:

An SFG should return an unfolded version of itself by calling sfg.unfold(). A parameter to the function should be number of unfolds.

An algorithm describing this can be found in lecture of 5 of TSTE87: https://www.isy.liu.se/en/edu/kurs/TSTE87/forelasning/TSTE87Lecture5.pdf

Issue Requirements:

1. Has to work exactly as described in the material of TSTE87.
