[gdal-dev] convert linestring to point data

[Tyler Mitchell]

Just a brief follow up for posterity on the list...

I've completed my first run of updates on this script and it's looking pretty good.  Others welcomed to give feedback :)

It's been modularised now and also allows you to enter a field name to take the Z value from.

So Murat, it does everything you need now, so grab a fresh copy!

The only other improvement I can think of is to specify an output format and create a non-CSV output instead.
