…b file outlets. These changes reinstate automatic releasing of "automatic" Nu instance variables; these are the variables created automatically when they are accessed for classes whose definitions include the (ivars) operator. Other instance variables are not automatically released when their owners are deallocated, because I learned that when they are set as outlets in nib files, their values aren't retained. This may require a separate declaration type ("outlet" or "weak" instead of "id") and until this is resolved, we potentially leak objects assigned to declared instance variables. An update to Nu to support GC would eliminate the need for this, but Nu also needs to work on platforms without GC. Also, on the subject of other platforms, the iPhone build is now broken because (until recently at least), the iPhone SDK does not support NSMapTables. That's too bad, because the NSMapTable interface is really nice, but portability is better, so I plan to replace them with the symbol tables implemented in the st.[hc] files.
