ParIterator::operator==

[Richard Kimberly Heck]

This method is commented out ostensibly because the current implementation

bool operator==(ParConstIterator const & iter1, ParConstIterator const & 
iter2)
{
     // FIXME: this makes two full copies!
     return DocIterator(iter1) == DocIterator(iter2);
}

made two copies, so was expensive. But what about:

bool operator==(ParConstIterator const & iter1, ParConstIterator const & 
iter2)
{
     DocIterator const * dit1 = &iter1;
     DocIterator const * dit2 = &iter2;
     return *dit1 == *dit2;
}

? That should work, yes? It does compile...

Is this a method we would like to have? If not, I'd propose just to 
remove the dead code.
