[plt-scheme] ProfessorJ, ==, and double

The == operator doesn't operate on type double in ProfessorJ: Beginner
in DrScheme v209.  It works fine in ProfessorJ: Advanced, but we've
needed it in our earliest examples in the HtDCH class.  We can work
around it with new Double(x).equals(new Double(y)), but yuck.  Is
there any reason for this being left out of the Beginner level?
