Introducing ErrorCode
The objective of error code class to wrap an integer that may bereturned from a function that may fail for different reasons. Since weare not able to return values different from 0 in case of error in thearduino language we need to wrap them into this class and redefineboolean operator to mantain the same behaviour

* Errors are generally represented with an int type that may vary in size depending on the platform.
