Vector library - reading features - simple feature access.
Higher level functions for reading/writing/manipulating vectors.
See read_ogr.c (OGR interface) and read_pg.c (PostGIS interface) for imlementation issues.

Reads feature from OGR/PostGIS layer on topological level.
This function implements random access on level 2.
Note: Topology must be built at level >= GV_BUILD_BASE
