+/* How to use the library
+Include Debug.h in any file that sends debugging messages 
+
+Start the debugging server in the main 
+    initDebug(); //initialize Debug server
+    startDebug(debug_port);  //start the Debug server 
+    while(!isDebugConnected()) //do nothing until a debug client is connected (optional)
+    {
+  
+    }
+    
+Send a debugging message to the connected client using sendDebugMessage(char *message)
+    Example: sendDebugMessage("Initialization failed");
