    Summary: Check that fixed joint constrains 2 bodies

    Level Description:
    lead - Starts above follower entity
    follower - Starts below lead entity. Constrained to lead entity with fixed joint. Starts with initial velocity of (5, 0, 0) in positive X direction.

    Expected Behavior: The follower entity moves in the positive X direction and the lead entity is dragged along towards the positive X direction.
    The x position of the lead entity is incremented from its original.

    Test Steps:
    1) Open Level
    2) Enter Game Mode
    3) Create and Validate Entities
    4) Wait for several seconds
    5) Check to see if lead entity and follower entity moved in positive X direction.
    6) Exit Game Mode
    7) 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.
