The objective of error code class to wrap an integer that may be returned from a function that may fail for different reasons. Since we are not able to return values different from 0 in case of error in the arduino language we need to wrap them into this class and redefine boolean operator to mantain the same behaviour
The objective of ReturnValue is to maintain coherency with ErrorCode class in cases where a single value is used to represent both the error and the return value
