[seam-dev] Excel support

[Dan Allen]

This is exactly the type of proposal I was envisioning. I second Pete
with regards to the CDK. It significantly reduces the pain of
developing JSF components and encourages the source code to be well
organized.

In my mind, this would be a huge feature for Seam...arguably more so
than any other tag-oriented feature we have so far. We definitely want
a lot of sensible defaults to comply with Seam's goal to reduce
typing. While some people want to tweak every cell, others just want
to spit out the data and mess with it in Excel (and get paid sooner).

Do we have a JIRA issue for this project? If not, we need one.
