Use an ID property for the subtree.

A small *.el file can set prereqs, find the subtree from the ID, and
call up the exporter.

`make test' does something like this. If you look at 
testing/lisp/test-ob.el, testing/examples/babel.org, and the testing/*.el 
files you can see some of this in action.
