A simple GBP example using Behavior Model and Structural Model. 

PEG(process event generator) model generates events periodically.
Buffer model stores and forwards Events generated by the PEG.
MsgRecv handles the event messages generated by the PEG.

Usage:
From a terminal in the parent directory, run the following command.

   pytest -s ./tests/test_hierachical.py
