That would be great -- I think having this bundled up in a library with
a decent API would be very useful to the community. I know I would use it.
I think I'd rather see it as an independent library, perhaps used by
Proj, rather than built in to Proj, but it's not a huge difference.
Now we just need someone with a bit of time to take a lead on developing
the API....
