[ndnSIM] node names find matching prefix

Hi Josh,

Unfortunately, as of right now, you have to do a little bit more job than that.  

You have to iterate over all nodes (NS-3 has a global variable for that) and check their names. Something like that:

for (NodeList::Iterator node = NodeList::Begin(); node != NodeList::End(); node++)
    if (Names::FindName (*node).compare (0, sizeof("consumer-"), "consumer-") == 0)
        consumerHelper.Install (*node);

If you can spend some time and implement a generic way for doing this in AppHelper, I would be happy to merge that code in.
