Numeric.AD.Internal.Doctest

Description

A version of Double that rounds to the twelfth digit if necessary. This is useful for ad's doctests since they must print out floating-point numbers in their entirety, but the actual numbers that get produced can vary slightly depending on machine-specific implementation details. (See #73 for an example.) This works around the issue by just rounding up the printed result to a point where it should be consistent across all machines.
