One step at a time! ;-)

You must add ScalarMaps before adding references.  If you want to
add a new ScalarMap, you need to remove the DataReferences, add
the ScalarMap and then add the DataReferences back in.

>Also, is there an index to the examples?  I.E. "Test00.java:
>Demonstrates 1, 2, 3"

java DisplayTest in visad/examples will list a short description
of all the examples of form Testnn.java
