[Hessianobjc-user] Bug decoding references to mapped class instances

[Tom D. <tgd...@gm...>]

When a map is decoded, the NSDictionary is stored in the refArray,  
even if the dictionary is subsequently mapped to a class. This means  
that references get the dictionary, not the class:

Here's a simple fix which defers storing the reference until the end:

  - (id) decodeMap {
      id dict = [NSMutableDictionary dictionary];
-    //add the pointer to the ref array and not the actually value.
-    [refArray addObject:[NSValue valueWithPointer:dict]];
      Class mappedClass = nil;
      uint8_t objectTag = 'e';
      if([dataInputStream hasBytesAvailable]) {
