+/** The steps below describe how to use this library:
+ * 1. Import this library to your project 'As file', because you will need to modify this file as described in step 2
+ * 2. Edit this library
+ * 3. Remove comment from line 57 (search for '//#define __DEBUG' in this file) to get the DEBUG macro defimed properly. By default, __DEBUG flahg is undef
+ * 4. Rebuild this library and use the debug macro as decribe in sample code
+ *
+ * IMPORTANT: If you modify this libray, please keep this comment up to date for future users
+ *
+ * Please refer to handbook (http://mbed.org/handbook/Debugging) for mbed Debugging support
