[Ref-Links] DOI's? - Let's pretend they're fun :)

[tony_hammond@harcourt.com]

Attached is a first-cut at a high-level API for DigitalObjects with
introduction, examples and reference. DOI implementation details are
abstracted away. Now we can just stay focused on the data. Main motivators
are simplicity and utility in dealing with multiple resolution contexts. As
the examples below show one can even achieve something useful with a single
statement. This work builds on previous posts regarding DOI infrastructure
and uses the same DOI type set. Hopefully worth a quick peek. Glad to get
any feedback.
