Detailed Description

constant iterator class for QoreHashNode, to be only created on the stack

   ConstHashIterator hi(h);
   while (hi.next()) {
   QoreStringValueHelper str(hi.getValue());
   printf("key: '%s', value: '%s'\n", hi.getKey(), str->getBuffer());
   }

DLLEXPORT bool ConstHashIterator::next (  ) 

moves to the next element, returns false when there are no more elements to iterate

also moves to the first element if the object has just been initialized after a complete iteration (assuming there is at least one element in the hash)
