Issue Type: Bug
Components:
There's a Trove feature I didn't address in the 0.3 version of collections:
control of the hash function for Object types. In Trove, you construct over
a 'strategy' object if you want something like the JDK IdentityHashMap. COLT
didn't do that. A user can get this currently via subclassing, though

best function.

could have used something like this baked into collections already. I
vote for the strategy pattern.

It's a little worse than 'override'.
I'm going to code subclasses in my code to get something done before we get
to the next Mahout release, and that will give me some practical experience
with the whole business.
Meanwhile, consider the case of IdentityHashMap. If nothing else, the
strategy approach means adding One class to the
