1. Make a wrapper class. Now you can store Object[], or you can 
make a
base class or base interface and use that.
2. Use Variant, which can wrap anything, or the related 
Algebraic, which
can wrap a fixed collection of types.
3. Use an union. However, only do this if you always know from 
outside what type of data is stored in each node. If you need to 
memoize the type of data for each node, better resort to 1. or 2.
