 *
 * This file should only be included in a project if there is a need to
 * initialize the Trace Recorder before main() has been called.
 * An example of this scenario is if you have a global object instance that has
 * a constructor that creates an object that should be traced.
 * This file will make it easier to initiate the recorder correctly.
 *
 * Usage:
 *	Add a call to TraceRecorderInit::Initialize() wherever a traced object is
 *	created before the Trace Recorder is normally initialized. This will ensure
 *	the Trace Recorder is initialized only once.
 *
 *	Set TRC_CFG_RECORDER_DATA_PTR_INIT to 0 in trcSnapshotConfig.h to ensure
 *	RecorderInitialized isn't initialized to 0 after the recorder has been
 *	already initialized.
 *
 *	Finally, call vTraceEnable(TRC_START) after hardware is initialized to
 *	start gathering trace events.
