Add Unit Tests for utilFncs.py

[royagrace]

Description

I added tests to test 8 uncovered functions from utilFncs.py

Motivation and Context

This should help to increase the coverage of total tested lines

How Has This Been Tested?

All changes are passing locally using the " pytest test/test_util.py " command.

I added code to test the different possible outcomes for each function called.
However, for the function show_progress() I was having problems being able to test the update() and
finish() member functions, so those tests have not been added yet.

Screenshots (if appropriate):

@royagrace I think you'll need to rebase on dev to get the failing tests to pass.
