title: Multiple inheritance and a heterogeneous collection
body: <p>I have three classes that inherit from both <code>whirlyB</code> and <code>gameCreature</code>.  I am using all three sub classes in a collection of <code>gameCreatures</code>.  Is there a way to use the inherited functionality from <code>whirlyB</code>.  I am only given the choice of using <code>gameCreature</code> functions.  What should I do to get the functionality of <code>whirlyB</code>?</p>
