Subject: Building spatial index only for vectors once

Hi,

now that the spatial index is no longer built automatically but generated at
run-time as needed, it would be nice if it would save the spatial index so
that subsequent calls didn't have to regenerate it everytime.

e.g. running d.what.vect on LIDAR data takes a long time to start up, when
running multiple queries you have to wait each time..

maybe this is just me missing the point of not generating the spatial index
upon vector creation: was the point to save time or disk space?


thanks,
Hamish
