It is used instead of pointers so that an object may be moved, copied, freed and reallocated and the names should act intelligently, for example in undo / redo names are preserved, but in copy / paste they are not.
When you copy-construct or assign a UniqueIdentifier instance, the source object's name is kept. This is useful for operations such as undo and redo, where a copy of a previously deleted object can be put back with the same name. However, sometimes a new name is wanted (for example when copy / paste is used, or you are creating a new object similar to a previous one and you want to keep using both copys.) In this case, make sure to use the default constuctor instead of the copy constructor (you may need a special constuctor).
