Improved how project path is added to sys.path

sys.path.append( os.path.abspath(os.path.join(os.getcwd(),
__file__)).rsplit("/",1)[0] )
The above line takes care of adding the project’s folder (that contains
all of the scripts and files) to the sys.path, such that objects and
scripts can be imported.
This functionality was founded and tested using the script
paths_test.py in Misc. Project Info

calcGraphValues:
- consolidated repeated code (stuff that was common to generating the
throughput values or delay values)
