/******************************************************************************
 *   Description:        This class provides Market Exchange Emulator
 *                       functionality. It accepts trade requests for
 *processing; generates a negative exponential delay for each trade to simulate
 *the market processing time; manages the timers for all trades being processed;
 *generates Trade-Result and Market-Feed input data to be used by a sponsor
 *provided callback interface to the SUT (see MEESUTInterface.h).
 *
 *                       The constructor for this class requires two parameters.
 *                       - TradingTimeSoFar: the number of seconds for which
 *                       trades have been run against the database. This allows
 *                       the MEE to pick up on the price curves from where it
 *                       last left off. If doing this isn't important than 0 can
 *                       passed in.
 *                       - pSUT: a pointer to an instance of a sponsor provided
 *                       subclassing of the CMEESUTInterface class.
 *
 *                       - pLogger: a pointer to an instance of CEGenLogger or a
 *                       sponsor provided subclassing of the CBaseLogger class.
 *
 *                       The MEE provides the following entry points.
 *
 *                       - SetBaseTime: used to cordinate the price curves
 *                       across multiple instances of this class. This method
 *                       should be called "at the same time" for all instances.
 *                       This call should be made just prior to starting
 *                       transactions. There is no return value.
 *
 *                       - SubmitTradeRequest: used for submitting a trade
 *                       request into the market. The return value is the number
 *                       of milliseconds before the next timer is set to expire.
 *
 *                       - GenerateTradeResult: called whenever the current
 *timer has expired (i.e. whenever the number of milliseconds returned by either
 *SubmitTradeRequest or GenerateTradeResult has elapsed). The return value is
 *                       the number of milliseconds before the next timer is set
 *                       to expire.
 *
 *                       - DisableTickerTape / EnableTickerTape: by default, the
 *                       ticker tape functionality of the MEE is enabled. It can
 *                       be disabled, or re-enabled by calls to these methods.
 *                       Disabling the ticker tape is useful at the end of a
 *                       test run to allow processing of submitted orders to
 *                       continue (Trade-Results) while not generating any
 *                       ticker tape activity (Market-Feeds).
