*
* @section DESCRIPTION
*   Definitions for various messaging levels. See the example, below for usage.
*
* @section EXAMPLE
*   1) Add this library to your project.
*   2) Include the file as a regular .h file in *.cpp files only. This will allow
*      you to have different messages coming from different files.
*
*   Ex: main.cpp:
*
*   #include "mbed.h"
*   
*   // Include the following #defines and #include to use messages.h in every *.cpp file you would like to use it in:    
*   //#define DEBUG             // This define is commented out, so DEBUG messages will NOT be displayed.
*   #define INFOMESSAGES        // The next three are defined, thus INFO, WARN, and ERR messages will BE displayed.
*   #define WARNMESSAGES
*   #define ERRMESSAGES
*   #define FUNCNAME "MAIN"     // Set this to an intelligible string. Usually set to something to do with the filename.
*   #include "messages.h"       // Finally include the messages.h header.

*   // Main Loop!
*   int main() {
*       INFO("CPU SystemCoreClock is %d Hz", SystemCoreClock);
*       DBG("Testing %d, %.3f, %d", 1, 2.0f, 3);
*   }
*
*
