eoAge is a template class that adds an age to an object.\\ Requisites for template instantiation are that the object must admit a default ctor and a copy ctor. 

The Object must be an \fBeoObject\fP, thus, it must have its methods: className, printOn, readFrom.

Default Constructor.

\\ Itīs private so that it is not used anywhere; the right way of using this object is to create an Object and passing it to an aged by means of the copy ctor; that way itīs turned into an Aged object

Return the class id.

This should be redefined in each class; but it's got code as an example of implementation. Only 'leaf' classes can be non-virtual.
