somPrintSelf should output a brief string containing key information useful to identify the receiver object, rather than a complete dump of the receiver object state as provided by somDumpSelfInt. The somPrintSelf method should use the character output routine SOMOutCharRoutine (or any of the somPrintf functions) for this purpose. The default implementation outputs the name of the receiver object's class and the receiver's address in memory.
Because the most specific identifying information for an object will often be found within instance data introduced by the class of an object, it is likely that a class implementor that overrides this method will not need to invoke parent methods in order to provide a useful string identifying the receiver object.
