+ *  Example:
+ *  @code
+ * #include "mbed.h"
+ * #include "Led.h"
+ *
+ * LED myled(PF4);
+ *
+ * int main(){
+ *  while(1){
+ *  wait(5);
+ *  myled.on();   //Turns the led on
+ *  wait(5);
+ *  myled.blink(1); //Blinks the led for 0.2 seconds
+ *  wait(5);
+ *  myled.toggle();   //Toggles the state of the led (turns it off)
+ *  }
+ *  @endcode
