    Summary: Tests the utility of the Physmaterial_Editor

    Level Description: Completely empty and used as method to run material editing methods from the editor

    Expected Results: All Physmaterial tests work as expected.

    Test Steps:
    1) Open Level
    2) Check that the correct files open
    3) Check library properties
    4) Check editor methods
    5) Check write() works as expected
    6) Close Editor

    Note:
    - This test file must be called from the Open 3D Engine Editor command terminal
    - Any passed and failed tests are written to the Editor.log file.
            Parsing the file or running a log_monitor are required to observe the test results.
