        Summary:
        Basic Workflow: Layers.

        Test Steps:
        1) Open level
        2) Create layer in the Entity Outliner
        3) Create entity and Drag the entity into the layer
        4) Create another entity and Drag entities out of the layer
        5) Create a second layer and Drag the second layer into the first layer
        6) Save layer

        Note:
        - This test file must be called from the Lumberyard 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.
