+/** A  Morse Encoding/Decoding Library \n
+    Transforms char arrays into bool arrays and vice-versa
+    
+    Morse code taken from http://en.wikipedia.org/wiki/Morse_code \n
+    Added some more characters : \n
+        minus : DOT DOT DASH DASH \n
+        _ : DASH DASH DASH DOT \n
+        . : DASH DASH DASH DASH \n
+        / : DOT DASH DOT DASH \n
+        @ : DOT DOT DOT DASH DOT \n
+        ? : DOT DOT DASH DOT DOT \n
+    
+    Here is an quick hello-world that show how to use this library \n
+    @code
+    #include "mbed.h
+    #include "Morse.h"
+    
+    Serial pc(USBTX, USBRX);
+

+        
+        data = morse_create(morse_getBoolSize(message));
+        morse_encode(message, data);
+        for (i=0; i<data->length; i++) pc.printf("%d", data->data[i]);
