Implementation of unittests for vizualization functions + modification of load tests to run for Windows users.

ofhkrrequested to merge
Viz_Unittests into main

In this branch the following were implemented:

  • All vizualization tools now return the figure instead of simply plotting.
  • Test functions have been implemented for all vizualization tools.
  • The test_save.py and test_load.py files were modified so the test functions also pass on Windows.
