I didn't get a chance to review/vote on this before it was merged, but I
dont' think this is what I expected to happen when I wrote the JIRA. I didn't
think we would produce direct support for `BigDecimal` so much as coerce
`BigDecimal` into double so that when Groovy did its magic to:
```groovy
g.withSack(2).V().sack(Operator.div).by(constant(3.0)).sack()
```
we'd just get back a double - not a `BigDecimal`. Directly supporting
`BigDecimal` means we need to support it as a GraphSON type. We already do, but
only in the extended module so if you wanted to use `BigDecimal` you'd have to
include that configuration. No GLV at this point supports the extended module
(though @davebshow is working on that). Do we really need to provide direct
support for `BigDecimal` when the problem we were trying to solve was related
to Groovy taking a literal and auto-assigning it to `BigDecimal` (sorta
unexpected)? or do users really need the ability to do
`constant(BigDecimal.valueOf(3))`?
