Detailed Description

This class implements Optional functionality for ParseResult.

We don't directly use Optional here, because it provides an implicit conversion to 'bool' which we want to avoid. This class is used to implement tri-state 'parseOptional' functions that may have a failure mode when parsing that shouldn't be attributed to "not present".
