/**
* Instances of the class XdrLong represent (de-)serializeable
* longs (64 bit), which are especially useful in cases where a result with only a
* single long is expected from a remote function call or only a single
* long parameter needs to be supplied.
*
* Please note that this class is somewhat modelled after Java's primitive
* data type wrappers. As for these classes, the XDR data type wrapper classes
* follow the concept of values with no identity, so you are not allowed to
* change the value after you've created a value object.
