I added more details about GiST use cases (PostGIS and ScalaGiST) in my
proposal and created one more entry for reviewing other patches in the time
table.

I'll try to polish the proposal in the remaining three days to the GSoC
deadline. I don't think I have much time to modify PostgreSQL source code
and test against it myself though ;(. Many thanks to your feedback.
