    While investigating ParseNodeFactory, it looks like all numbers are parsed as real numbers
(big decimal), or whole numbers (slightly more logic to try to fit them into ints, Longs,
or BigDecimals).  Just to clarify, you want me to create a new method in ParseNodeFactory
to try to parse doubles, then update the Antlr tree to use that new method?
