* new objects with unique identifiers. The idea is to simply inherit the
|
|
* new object class from the identifier class.
|
|
*
|
|
* At construction-time the class tries to generate a new unique
|
|
* identifier. Hereafter it is the users responsibility not to mess
|
|
* up the id-name string. However, end-users can always be sure that
|
|
* the index value provided by the identifier class is unique.
