    **Validation Test Description**
    The unit test  for this module is kept as there are no branching code segments to account for different cases.
    The spacecraft inertia tensor message is setup, as well as a guidance message.  The module is then run for a
    few time steps and the control torque output message compared to a known answer.  The simulation only variable
    is if the known external torque is specified, or if the zero default vector is used.
    **Test Parameters**
    The unit test verifies that the module output torque message vector matches expected values.  The test
    method parameters include the following.
    :param show_plots: flag to show the test run plots
    :param setExtTorque: flag to set the knownTorquePntB_B variable
    :return: void
