Initial value for HasValueChanged

When an Expression or Event Frame Generation analysis evaluates for the first time, the function HasValueChanged returns True even if the value has not actually changed. More proper behavior would be to default to false. The same holds true when manually backfilling causing incorrect values to be generated.
