com.google.gwt.coreext.client.JsIntegerDoubleMap
Overlay type to deal strictly with double primitives and int keys. We can use this instead of JsIntegerMap in scenarios where we do not want to pay the penalty of Double<->double autoboxing semantics. Since Java generics do not support primitive types, JsIntegerMap can only hold values of type Double. Additionally, pulling Doubles out of maps require that we need to do nullity checks, and thus the GWT compiler must compile this to something that is a Class wrapper for a double primitive, when what we really want is just a plain double.

      // Leaf node check
