/**
* This is a convenient base class for all classes
* that wish to establish an initial identity which
* will be the basis of a one-per vm identity: i.e.
* in any vm there should only ever be a single object
* with a given identity token (except transiently during
* canonicalization)
*
* It would be convenient to put the getter/setter methods
* for the identity token here, but unfortunately we have no
* way of setting up the for Referenceability in multiple
* levels of a class hierarchy. So we leave the getters/setters,
* and variable initialization to code-generators.
