 * Call the trace initialization (`mbed_trace_init`) once before using any other APIs. It allocates the trace buffer and initializes the internal variables.
 * Define `TRACE_GROUP` in your source code (not in the header!) to use traces. It is a 1-4 characters long char-array (for example `#define TRACE_GROUP "APPL"`). This will be printed on every trace line.
