    \class StatusTestOutput
    \brief A virtual base class for StatusTest that print other status tests.     

    StatusTestOutput provides an interface for status tests that wrap another StatusTest.  These
    printing status tests can be generic, calling StatusTest::print() on the underlying object, or 
    can specifically require input status tests to be of a certain type. The frequency and occasion 
    of the printing can be dictated according to some parameters passed to 
    StatusTestOutput::StatusTestOutput().

  /*! \brief Constructor
   *
   * The StatusTestOutput requires an OutputManager for printing the underlying StatusTest on
   * calls to checkStatus(), as well as an underlying StatusTest.
   *
   * The last two parameters, described below, in addition to the verbosity level of the OutputManager, control when printing is 
   * called. When both the \c mod criterion and the \c printStates criterion are satisfied, the status test will be printed to the 
   * OutputManager with ::MsgType of ::StatusTestDetails.
   *
   * @param[in] mod A positive number describes how often the output should be printed. On every call to checkStatus(), an internal counter
   *                is incremented. Printing may only occur when this counter is congruent to zero modulo \c mod. Default: 1 (attempt to print on every call to checkStatus())
   * @param[in] printStates A combination of ::StatusType values for which the output may be printed. Default: ::Passed (attempt to print whenever checkStatus() will return ::Passed)
   *
