/**
* SysMLinJava value type for the SysML Integer.<br>
*
* <p>
* * Note that the {@code Integer} name clashes with the
* {@code java.lang.Integer} name. Therefore, this SysMLinJava version uses the
* double I spelling.
* <p>
* This representation of the integer type is for a generic integer as used in
* SysML. Hence the use of a Java long for its value. This SysML integer is not
* the same as the java int or Integer types as SysML does not discriminate
* between bit-lengths of numeric types as does the Java language.
* <p>
* <b>Note:</b> as an {@code ObservableValue} implementation, this value type
* can be "observed" by other objects. {@code ValueObserver}s call the
* {@code addValueObserver()} operation to be notiified (called-back) by the
* {@code Int} object of any change in its value. This notification will only
* occur if and when the {@code IInteger value} is changed by a call to the
* {@code setValue()}, {@code increment()}, or {@code decrement()} operations.
* So, while the {@code IInteger value} is publicly accessible and can be
* changed by direct assignment, one of the value changing operations must be
* used if {@code ValueObserver}s are to be notified of the change.
