+/**
+ * @file
+ * 
+ * TAKING LOGGING INTO USE:
+ * 
+ * This step is needed to do once per component.
+ * 
+ * For each component that uses these common logging macros should specify
+ * their own logging configuration file, which includes this file. In that
+ * configuration file, following constants and macros must be defined.
+ *  For example:
+ * @code
+ * 
+ * _LIT( KHgLogFile, "text_file_for_logging.txt" );
+ * _LIT( KHgLogPath, "folder_for_text_file" );
+ * #define _HGLOG_LOG_COMPONENT_ID <some unique number here>
+ * 
+ * #include "hglogging.h"
+ * 
+ * @/code
+ * 
+ * KHgLogFile   : This is the name of the file, where all the logs for
+ *                this components are being written.
+ * 
+ * KHgLogPath   : This is the folder name under c:\logs, where the file
+ *                is to be stored. For example, if KHgLogPath is "test",
+ *                log file is created into folder c:\logs\test.
+ * 
+ * _HGLOG_LOG_COMPONENT_ID  : Unique number id of the component. This is 
+ *                            for filtering purposes.
+ * 
+ * _HGLOG_RDEBUG    : When defined tracing instead of file logging. 
+ *                    Default is for file logging.
+ * 
+ * --------------------------------------------------------------------------
+ * 
+ * USING LOGGING:
+ * 
+ * Basically the use is simple, register function use with HGLOG_CONTEXT, 
+ * then log function enter by any HGLOG_IN -macro, then possibly use HGLOG
+ * -macros for function logging and finally HGLOG_OUT -macros for returning
+ * from the function.
+ * 
+ * @code
+ * TInt CGood::Example( TInt aSomething )
+ *     {
+ *     // Create log context class, which is maintained for lifetime of the 
+ *     // method. 
+ *     HGLOG_CONTEXT( Example, HGLOG_LOCAL );
+ * 
+ *     // Indicate we are entering the function. 
+ *     HGLOG_IN1( "aSomething contains value %d", aSomething );
+ * 
+ *     // Your buggy code...
+ * 
+ *     // Before leaving, indicate function execution has ended.
+ *     HGLOG_OUT();
+ * 
+ *     return 0;
+ *     }
+ * @/code
