[seam-dev] Excel implementation

[Dan Allen]

Norman, if you are listening, perhaps this is the use case you needed
to justify moving forward with the refactoring of DocumentStore.

Like Pete mentioned in another e-mail, it might be best if we avoid
copy/paste and do the XLS module using the CDK. I think its reasonable
to assume that we need an XLS module, unless we want to bundle PDF and
XLS together as some sort of rich export module.
