Documentation should make it clear that NumberOptions needs to be set to AllowSign in order to parse negative values

[Paul Marfleet]

The Integer and Decimal examples in the documentation are incorrect. They give the impression that Terms.Integer() and Terms.Decimal() will successfully parse negative values. However, parsing negative values requires NumberOptions to be set to AllowSign, e.g. Terms.Integer(NumberOptions.AllowSign).

I'll check the source to be sure it's intentional. Seems weird. Might be a bug more than a lack of documentation.

I fixed the documentation, this was intentional.
